How to Fix Run Time Error 429

Hello and welcome everyone, today we will be talking about power toys, a great, completely free, open-source, Microsoft-supported Windows project which aims to provide Windows itself with powerful features not found natively in it. We will explore power toys completely here and explain each module and its features. The first thing is of course to download power toys themselves. You can find them here. After you download them, double click on the downloaded file and install. Start power toys, you will find them at the bottom of the taskbar, note that power toys need to be active in order to use their features. When opened you will be greeted with general settings window. These are settings for power toys themselves, Here you can check for updates, change the looks of power toys, run it on system startup and run them as administrator. Set them up so they best suit your needs.

Color Picker

Moving down next tab we have is Color picker. The color picker will let you as the name suggests pick colors, it will sample colors from running applications and windows, snap their values, and place them in the clipboard. A useful application if you are working as a graphic designer, want to create some cool word document, or just want to compare the difference between colors. After the Color Picker is activated, hover your mouse cursor over the color you would like to copy and left-click the mouse button to select a color. If you want to see the area around your cursor in more detail, scroll up to zoom in. The copied color will be stored in your clipboard in the format that is configured in the settings (HEX by default). The editor lets you see the history of picked colors (up to 20) and copy their representation in any predefined string format. You can configure what color formats are visible in the editor, along with the order that they appear. This configuration can be found in PowerToys settings. The editor also allows you to fine-tune any picked color or get a new similar color. Editor previews different shades of currently selected color - 2 lighter and 2 darker ones. Clicking on any of those alternative color shades will add the selection to the history of picked colors (appears on the top of the colors history list). Color in the middle represents your currently selected color from the history of the colors. By clicking on it, the fine-tuning configuration control will appear, which will let you change the HUE or RGB values of the current color. Pressing OK will add newly configured color into the history of the colors.

Fancy Zones

Moving down, we have fancy zones. FancyZones is a window manager utility for arranging and snapping windows into efficient layouts to improve the speed of your workflow and restore layouts quickly. FancyZones allows the user to define a set of window locations for a desktop that are drag targets for windows. When the user drags a window into a zone, the window is resized and repositioned to fill that zone. When first launched, the zones editor presents a list of layouts that can be adjusted by how many windows are on the monitor. Choosing a layout shows a preview of that layout on the monitor. The selected layout is applied automatically.

File Explorer

Next, File Explorer. Only 3 options here but maybe some are important to you. This extension lets you enable SVG file preview in File Explorer, enable Markdown preview, and enable SVG thumbnails. Turn on each one you might need.

Image Resize

Next down the line, we have Image resize. Image Resizer is a Windows shell extension for bulk image-resizing. After installing PowerToys, right-click on one or more selected image files in File Explorer, and then select Resize pictures from the menu. You can specify your own sizes if you want, you can resize when dragging files, you can overwrite files or make new copies of new sizes, and many more options. A very useful tool I am sure plenty of users can use since this eliminates the need for pictures or any other image application for common resizing tasks.

Keyboard Manager

The keyboard manager is the next tab in power toys. The PowerToys Keyboard Manager enables you to redefine keys on your keyboard. For example, you can exchange the letter A for the letter D on your keyboard. When you select the A key, a D will display. You can also exchange shortcut key combinations. For example, the shortcut key, Ctrl+C, will copy the text in Microsoft Word. With the PowerToys Keyboard Manager utility, you can exchange that shortcut for ⊞ Win+C). Now, ⊞ Win+C) will copy text. If you do not specify a targeted application in PowerToys Keyboard Manager, the shortcut exchange will be applied globally across Windows. PowerToys Keyboard Manager must be enabled (with PowerToys running in the background) for remapped keys and shortcuts to be applied. If PowerToys is not running, key remapping will no longer be applied.

Power Rename

Nex we have a very cool and powerful Power Rename PowerRename is a bulk renaming tool that enables you to:

• Modify the file names of a large number of files (without renaming all of the files with the same name).
• Perform a search and replace on a targeted section of file names.
• Perform a regular expression rename on multiple files.
• Check expected rename results in a preview window before finalizing a bulk rename.
• Undo a rename operation after it is completed.

Run Utility

Power Toys Run utility follows next. PowerToys Run is a quick launcher for power users that contains some additional features without sacrificing performance. PowerToys Run features include:

• Search for applications, folders, or files
• Search for running processes (previously known as WindowWalker)
• Clickable buttons with keyboard shortcuts (such as Open as the administrator or Open containing folder)
• Invoke Shell Plugin using > (for example, > Shell:startup will open the Windows startup folder)
• Do a simple calculation using the calculator

Shortcut Guide

Last but not least we have a Shortcut guide. This guide uses PowerToys to display common keyboard shortcuts that use the Windows ⊞ key. Windows key keyboard shortcuts can be used while the guide is being shown and the result of those shortcuts (active window moved, arrow shortcut behavior changes, etc) will be displayed in the guide. Releasing the Windows ⊞ key will make the overlay disappear. Tapping the Windows ⊞ key will display the Windows Start menu. Hey, you made it till the end, thank you for reading and I hope to see you soon.

Error Code 0x80240020 – What is it?

Error code 0x80240020 is a Windows 10 upgrade error code that affects users who attempt to upgrade their Windows operating system.

Method Three: Download an Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

You probably heard about switches for LAN but not a lot of people heard about KVM switches. So what exactly is KVM switch?

If we look at the name, it is a shortcut for Keyboard, Video & Mouse and the original idea was to have multiple computers but one keyboard, mouse, and monitor. These peripherals would be connected to the KVM switch and other computers could all use one set of these on the fly when needed.

The technology behind the switch is a little interesting since it will actively fake signals to other computers that are not using peripherals. Once they are switched to them the transition is smooth and not noticeable. In old days these switches were more important than today since on every mouse or keyboard disconnection you had to reboot the computer, and although today that is not the case CPU will still detect disconnection and on the next connection it will run through the ID of the device and try to use the existing driver and if peripheral was connected in other USB port, it will install the same driver but connect it to the new USB port.

This type of reconnection can slow down work and place unnecessary load on the CPU so that is why KVM will fake connection in order to make switching externals on the computer smooth and in nick of a time.

Modern KVM switch

These days modern KVM switches will offer you more options than just being able to switch between keyboard, mouse, and monitor. Modern switches now offer Lan, audio, and many more various options.

There are also different kinds of switches offering you only one option, like for example just a Video switch that will let you use one monitor on three computers and many more other specialized options.

Software switches

So far we talked about Hardware switches, a real device being able to take peripherals into it and switch computers on the fly. On the other line, we have software switch solutions that will have specific software installed on all computers and have it run at all times, and switching between them will be through specific software.

There are two very good and main advantages of using software solutions instead of a hardware one. First, of course, is the price, since the most popular Synergy is an open-source solution, completely free of charge. The second big advantage is that software switch is not limited to how many computers can you use. Hardware switches tend to go to a large number like 16 but if you have a large cluster of computers over a LAN, let's say 30 then the box solution might be difficult.

On the other hand software solution will switch only keyboard and mouse since each other computer will have to have some screen on it in order to work. Both solutions have their strong advantages and disadvantages and it is up to you to choose one that best suits you.

Conclusion

If you are multitasking with a lot of computers or just need your peripherals from time to time to connect to another machine then the KVM switch is something that you might find the use of. Just be aware that if you go for some cheap switch you might experience some lag on your peripherals, but if that is not a concern you can get hardware one for as low as $50 USD.

In case you don’t know, the Title bar comes with the Maximize, Minimize, as well as the Close button. However, there are instances when you might notice that the Title bar, Maximize, Minimize and Close buttons are missing in the File Explorer. This kind of problem might be due to some glitch in the computer, or it could also be caused by some built-in tool or an installed program in your computer. Moreover, there are also other factors that you have to consider such as corruption in the system files as well as errors in the user profile which is generated on a domain network, and so on. There are several suggestions you can check out to fix the problem. You can try to boot your computer in a Clean Boot State to see if a third-party program is the root cause of the problem. You can also try to run built-in tools like System File Checker and the DISM tool. You could also get the video buffer emptied, reset or reinstall the program, or recreate the User Profile.

Option 1 – Put your computer in a Clean Boot State

As pointed out, it is possible that some third-party program or service is the one that’s behind the problem. To isolate this possibility and to identify the culprit, you have to put your computer into a Clean Boot State. To do so, follow the steps below.

• Log onto your PC as administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• You need to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it.

Option 2 – Run System File Checker scan

You might also try running the System File Checker or SFC scan to fix the issue. System File Checker is a command utility built into your computer that helps restore corrupted files and missing files. Refer to the following steps to run it:

• Hit the Win + R keys to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Restart your computer and see if the System32 folder still pops up at startup or not.

Option 3 – Try running the DISM tool

You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the Windows Upgrade problem. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 4 – Try to empty the Vide buffer

These kinds of problems could also be due to bad data in the Video Buffer. Thus, you can try to empty the Video buffer to resolve the problem. All you have to do is tap the Shift + Ctrl + Win key + B keys on your keyboard. After that, leave your computer idle for about 10 seconds until you notice it blink once. Now you try using your computer as usual and see if the glitch is now fixed or not.

Option 5 – Try to reset or reinstall the program

Another thing you can do to fix the issue is to reset or reinstall the program where you encounter the problem. Chances are, you are running the application in the Full-screen mode but you can exit it by simply tapping the Esc or F11 key. However, if nothing changed, then consider resetting or reinstalling the program. Just go to the Windows 10 Settings app and navigate to Apps > Apps & Features. From there, look for the entry of the application you’re having problems with and select it and then click on the Advanced options. After that, click on the Reset button under the Reset section.

Option 6 – Try recreating the User Profile

You might also want to try recreating the User Profile on your computer since some errors in the creation of a User Profile can result in problems like this one. Thus, you have to try deleting the User Profile and then recreate it.

When we get ourselves a new USB stick, new hard drive, or any storage device not including optical drives they are usually preformatted and ready to be used out of the box. However, reformating them has several benefits and while we are reformatting we can choose in which file system format we want the memory to be formatted. In this article, we will compare and explore 3 typical and standard format options you can get while formating a new media in Windows 10.

FAT32

The oldest one on the list, coming all the way from DOS days. Great for devices that need to be plugged in different operating systems and for USB flash drives. Its advantages are compatibility with all major operating systems and little memory usage comparing to other ones. However, the file system is limited to file sizes of the maximum capacity of 4GB and partitions can not exceed more than 32GB.

NTFS

First introduced in Windows NT this file system offered slower performance than FAT32 and somewhat limited usability but the main advantages were more stability and fewer errors. Its main advantages are support for files larger than 4GB and partitions larger than 32GB along with the ability for on the file encryption, main disadvantage would be limited operating system usage, NTFS can not be used on systems that work on FAT32 like MS-DOS for example or older versions of Windows. The best usage for this file system is in internal hard disk drives and system drives.

exFAT

New kid on the block, well at least from the perspective of the previous 2. exFAT offers unlimited file sizes and unlimited partition sizes but at a price that is even more limiting than NTFS. Some Linux distributions will require a driver to be installed in order to see the exFAT partition. The best use is in storage, in external hard drives. That's it, 3 major file systems, we hope that you have managed to learn something new today, and remember to drop by tomorrow for more articles about advice, tips, tricks, and troubleshooting.

The dxgmms2.sys file is a system driver file in Windows that is associated with the Graphics Rendering capabilities of a computer. However, this file is known to cause various Blue Screen of Death errors. Some of the culprits for these errors include issues with RAM, hard disk issues, corrupted drivers, and incompatible firmware. Despite its many causes, fixing this issue is quite straightforward so it should be easier for you to fix it. Here are some of the Blue Screen errors related to the dxgmms2.sys file:

• SYSTEM_THREAD_EXCEPTION_NOT_HANDLED
• SYSTEM_SERVICE_EXCEPTION
• KMODE EXCEPTION NOT HANDLED
• PAGE FAULT IN A NONPAGED AREA
• IRQL NOT LESS OR EQUAL

If you have recently created a System Restore point prior to getting the dxgmms2.sys Blue Screen error, then you need to perform System Restore first before you further troubleshoot the problem as it might help in resolving the Blue Screen error. Refer to the steps below to perform System Restore.

• First, press the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

If System Restore didn’t help in fixing the Blue Screen error, now’s the time for you to resort to the troubleshooting tips provided below but before you get started, make sure that you create a System Restore point first.

Option 1 – Reinstall the Graphics Card drivers

• Tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.

Note: You also have the option to go directly to the website of your graphics card manufacturer and check if there’s a new update – if there is, download it. After that, you could also check if there’s a new update of the game you’re getting the issue of the black bar.

Option 2 – Try running the DirectX Diagnostic Tool

Since the dxgmms2.sys Stop error has something to do with the DirectX Graphics APIs, you can run the DirectX Diagnostic tool to resolve the problem.

Option 3 – Try updating or re-installing DirectX

If the DirectX Diagnostic tool didn’t work, you can try to update or reinstall DirectX instead. This can help in fixing the problem because when you reinstall or update DirectX, it will replace the incompatible or corrupted components of DirectX from your computer.

Option 4 – Try to update the BIOS

Updating the BIOS can help you fix the Blue Screen error related to the dxgmms2.sys file but as you know, BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
• After that, you should see the developer and version of the BIOS installed on your PC.
• Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
• If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
• Now double click on the downloaded file and install the new BIOS version on your computer.
• Now restart your computer to apply the changes made.

Option 5 – Use some registry tweaks

• Tap the Win + R keys to launch the Run utility.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlGraphicsDrivers
• From there, right-click on the right-side panel and click on New > DWORD (32-bit) Value.
• Then set the name of the new DWORD to “TdrDelay”.
• After that, use the next set of instructions and select the one for the Windows version you are using.

32-bit Windows:

• Choose the DWORD (32-bit) value.
• Then type in “TdrDelay” as the name and hit Enter.
• After that, double click on TdrDelay and add “10” as its value and click OK. This will set the response time for your GPU to be 10 seconds.

64-bit Windows:

• Select the QWORD (64-bit) value.
• Next, type in “TdrDelay” as the name and hit Enter.
• Double click on TdrDelay and type in “10” as its value data and click OK.
• Restart your computer to apply the changes made.

Option 6 – Disable the Sleep Functionality

You might also want to disable the Sleep Functionality as it could be the reason why you’re getting the Blue Screen error. There are times when the graphics card’s drivers are being used in the background and if the display goes to sleep and is awakened, it may cause a Blue Screen error. To fix it, you can prevent your computer from going into Sleep mode.

Option 7 – Try to run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that might help you fix any Blue Screen errors related to the dxgmms2.sys file. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Caching is used to enhance the performance of applications in Windows and other operating systems. It helps applications to load faster but there are times when the cache can get damaged or corrupted and as a result, you might encounter some issues. One of them is in the Firefox browser where the “Your Firefox profile cannot be loaded, It may be missing or inaccessible” error message may appear. You could also encounter this kind of error when Firefox is unable to access or find the profile folder. In case you don’t know what the profile folder is, it is where Firefox stores your user data and settings by default. Firefox pulls information from this folder each time you choose to open it. You can find this default Firefox profile folder under the %APPDATA%MozillaFirefoxProfiles folder. If you experience issues when trying to access the Profile Manager, you have the option to create a new default Firefox profile folder. This will fix the “Your Firefox profile cannot be loaded, It may be missing or inaccessible” error. How? Simply follow the given steps below. Step 1: Tap the Win key or click the Windows Start button to open the Start menu. Step 2: Next, type “%appdata%” in the field and hit Enter to open the hidden AppDataRoaming folder. Step 3: Now double click the Mozilla folder as well as the Firefox folder. Step 4: From there, look for the “profiles.ini” file and delete it. Make sure that you don’t delete the Profiles folder which should have the icon of a file folder. Note: Keep in mind that the .ini file extension is identified as the file that features a gear icon beside the “Configuration settings” or “Application settings”. Step 5: Once you open Firefox, a new profile will be created. On the other hand, if you know where your profile exists, you can try the following steps below to help Firefox locate it.

• First, you need to move the profile folder back to its original location.
• Next, restore the profile folder’s original name if you have modified it.
• Then create a new profile using the Profile Manager and give it an appropriate name.
• Now click on the Choose Folder button and select the profile folder you have moved or renamed before you exit the Create a new profile wizard.

As you know, a Virtual Private Network or VPN is used to access a particular network from another network which is why it is also referred to as a mini-internet. Moreover, you can use it in two ways. One, you can use it to get you access to a closed server which means that you would not be getting access to the internet. Second, you can also use it to access a set of resources while at the same time get access to the internet. However, what if you want to access your resources at home even when you’re away? And what if you want to use the private server at home or at your office even when you’re away? This is where the callout for a VPN server for yourself comes in. And so in this post, you will be guided in how you can create a public VPN server on your Windows 10 computer. Follow each one of the given steps below to get started. Step 1: Find your IP address. This step is rather simple since all you have to do is open Control Panel > Network and Internet > Network and Sharing Center. From there, click on “Local Area Connection” and then click on Details where you’ll see your IP address next to “Autoconfiguration IPv4 Address”. Step 2: Next, set up port forwarding on your router. In this step, you will have to configure port forwarding in your router so that you would be able to connect to the VPN server through a public network like the internet.

• Log in to the Admin Panel of your router. You have to do this since your router will be the gateway for your access to the network.
• After you’re logged in, look for the “Port Forwarding” or “Applications and Gaming” or “NAT/QoS” menu tab and other similar names.
• Now you need to set the port number to 1723 for connections based on Point to Point Tunneling Protocol.
• Then save the configuration and reboot your router.

Step 3: Set up a VPN server on Windows 10.

• In the Cortana search box, type “ncpa.cpl” and click on the related entry from the search results.
• After that, tap the Alt + F keys to bring down the File Menu and then select New Incoming Connection which will open a mini window where you can allow the user accounts on the particular machine to access the VPN connection.
• On the other hand, you can also click the “Add someone” button so that you can add someone else to the whitelist that can access the connection.
• Now click on Next and you’ll see an option to select how people will connect to the network. Check the checkbox for the “Through the Internet” option.
• After that, you will see a page where you have to configure the network. Just select IPv4 and then click on Properties.
• From there, you will be asked to continue some additional settings like letting users access your Local Area Network or how IP addresses will be allocated to these users. Click on OK to save the changes you’ve made.
• Click on Allow Access after you configure the network. And if you want to, you have the option to print this information for future reference or for the client machine.
• Now click on Close to exit the configuration process.

Step 4: Allow the VPN Connections through the firewall In this step, you will have to allow the VPN connections through the firewall.

• In the Cortana search box, type “Allow an app through Windows Firewall” and click on the related search result to open the intended Windows Firewall settings.
• Next, click on Change Settings.
• Then scroll down to check if Routing and Remote Access is Enabled for both the Public and Private networks and click on OK.

Step 5: Set up a VPN connection on Windows 10 Now all that’s left for you to do is to set up a VPN connection on Windows 10.

• Go to Settings > Network and Internet.
• From the list of options given, click on VPN located on the left pane to see the related settings.
• After that, click on the “+” icon to add a VPN connection.
• Next, select Windows Default under VPN Provider and under the Connection Name, input your VPN’s name, and then enter the IP address you got from the VPN service provider under the Server name or address section.
• Now select PPTP under VPN type since it is the most commonly used protocol for VPNs.

There are cases when you want to undo some changes you’ve made to your computer and to do that you have to perform the System Restore task. However, if you encounter an error that states “To use System Restore you must specify which Windows installation to restore”, when doing so, read on as this post will help you fix the problem. This kind of error in System Restore could be due to corrupted files in the system. There are also situations where you are not able to boot up once you encounter this error which could be a big problem. On the other hand, this error might have something to do with corrupted BCD files. Whatever the cause is, here are some potential fixes you have to try.

Option 1 – Try to run System File Checker offline

Like pointed out, since the error might be due to corrupted system files, you can try to run System File Checker offline. How? Refer to these steps:

• You need to go to the Advanced Startup Options and from there select Troubleshoot.
• Next, select the Advanced Options and then Command Prompt.
• After opening Command Prompt, type the commands given below and tap Enter right after you type each one of them.
  • Cd /
  • Dir

• If you can see the “Users” folder, that is your system’s drive. However, if you can’t see it, you can just change the drive-by assigning “D” as its alphabet volume.
• Then execute this command where “C” is the system drive: sfc /scannow /offbootdir=C: /offwindir=C:Windows
• Now repeat the given steps sequentially.

Option 2 – Try to run DISM tool

You can also run the DISM tool to repair the potentially corrupted system image. First, you have to check the health of the system like checking the integrity of the system files and Windows services. To run DISM, follow the given steps below sequentially.

• Open Command Prompt from the Advanced Startup options.
• After that, execute this command where “C:” is the system volume: DISM /Image:C:Windows /Cleanup-Image /RestoreHealth /Source:C:WindowsWinSxS
• If you encounter an error after executing the given command, insert the Windows USB or DVD and then execute this next command where “E:” is the USB or DVD drive: DISM /Image:C:Windows /Cleanup-Image /RestoreHealth /Source:esd:E:SourcesInstall.esd:1 /limitaccess
• In some cases, “install.esd” would be “install.wim” and in such case, you have to modify and execute this command: DISM /Image:C:Windows /Cleanup-Image /RestoreHealth /Source:wim:E:SourcesInstall.wim /limitaccess

Option 3 – Try to repair corrupted BCD

As mentioned, the error could also be due to corruption in BCD, and to fix it, you can use Bootrec.exe – a built-in command-line tool used to troubleshot issues related to boot up and Windows Startup. Before you run this tool, make sure that you have inserted a bootable USB or DVD into your computer. Once you have that covered, follow these steps:

• You need to go to the Advanced Startup Options.
• Then click on Troubleshoot.
• Next, select the Advanced Options and then Command Prompt.
• Once Command Prompt has been pulled up, enter each one of the following commands and in the sequence that they are given to rebuild BCD files and repair MBR files:
  • Bootrec /Fixmbr
  • Bootrec /FixBoot
• After you execute the commands given above, you should see a confirmation message that says, “The operation completed successfully”.
• Now type the “Bootrec /RebuildBCD” command to rebuild BCD.
• Finally, close Command Prompt and then restart your computer to successfully apply the changes made.

Option 4 – Try to run the Automatic Repair Utility

You might also want to use Automatic Repair in fixing the error. To do so, follow the steps below.

• You can start by creating and booting from a bootable Windows 10 USB Stick.
• After that, click on Repair your computer located in the bottom left corner when you are on the initial Windows Startup screen.
• Next, click on Troubleshoot, and then on the other screen, click the Startup Repair option.
• Now select the operating system you want to repair. Once you do that, it will start to repair your operating system. Wait until the process is completed and then check if the problem’s now fixed.

Option 5 – Try to use the Windows Recovery Environment

If the four options given above didn’t help fix the problem, you could try running Windows Repair and a Windows bootable USB or DVD.

• First, insert the bootable USB or DVD and boot into it, and select the “Repair your computer” option.
• Next, once you see the manufacturer logo on your computer, tap the key to enter into Windows Recovery Environment.
• After that, change the Boot sequence to DVD drive under the UEFI Firmware settings and restart your computer.
• Once your computer has restarted, select the boot order and make changes accordingly as displayed in the BIOS.

Option 6 – Try running System Restore in Advanced Startup Options

Since you probably can’t boot into your Windows 10 computer, you can try to run System Restore again in the Advanced Startup Options.

• Boot your computer into the Advanced Startup Options screen.
• From there, you will see some options to troubleshoot when you can’t log in to Windows in the usual way.
• Now select Troubleshoot > Advanced Options > Command Prompt.
• After that, type “exe /OFFLINE:C:Windows” and hit Enter to execute the command which will start the System Restore process.

Note: You need to replace “C” with the drive where Windows Installation is located.
