Fix Boot Device Not Found 3F0 Error

This post will show you how to fix the Windows update error 0xca00a000 which you can encounter during the installation of Windows updates. Here’s the full error message of this Windows Update error:

“Updates failed There were problems installing some updates, but we’ll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: 2018-07 Cumulative Update for Windows 10 Version 1803 for x64-based Systems (KB4345421) – Error 0xca00a000”

This kind of Windows Update error pops up when Windows has missed installing one of the cumulative updates needed or when there is some problem with the driver that won’t let the installation of the updates push through. There are also instances when the system files are modified with incorrect permission that may result in the Windows update error 0xca00a000. Thus, you need to fix the trusted installer permission as well as resolve the issue with the driver. To do these things, you need to follow the options laid out below.

Option 1 – Run the Windows Module Installer

The Windows Module Installer is a built-in service in the Windows operating system that could help you resolve the Windows update error 0xca00a000. You need to make sure that this service is Started and that its Startup type is set to Automatic – you can do this via Services Manager or by executing the command given below in an elevated Command Prompt.

• Tap the Win + R keys to open the Run dialog box.
• Then type “command prompt” in the field and hit Enter to open Command Prompt.
• And in the elevated Command Prompt type in the following command and hit Enter:

SC config trustedinstaller start=auto

• After executing the command successfully, you should see the “[SC] ChangeServiceConfig SUCCESS” message on the Command Prompt window.

Option 2 – Try manually installing the updates

As mentioned, the error might be because Windows missed installing a particular update which is why you are not able to proceed with the current update. So to resolve the issue, you need to install the update that wasn’t installed by downloading it from the Microsoft Update Catalog website. You also have to make sure that you didn’t turn off the Windows update or have it delayed.

Option 3 – Delete the files from the Software Distribution folder

The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. A lot of users tried deleting the files in this folder to fix the problem and so far it has worked. Like them, you can try clearing the Windows Update cache by simply deleting the contents of the folder named “SoftwareDistribution” since Windows apparently can’t clear and re-download the update contents once they are corrupted. Thus, deleting the contents of this folder will make Windows download the contents again which will fix the problem. To do that, follow the steps below.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net stop bits

• After entering these commands, it will stop the Windows Update Service and the Background Intelligent Transfer Service.
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
• Once all the contents in the Software Distribution folder are deleted, restart your PC and then go back to Command Prompt and input the following commands again.

net start wuauserv net start bits

Since the folder has already been flushed, it will be populated afresh the instant your restart your computer and open Windows Update.

• Now Open Settings and check for Windows Updates. Windows 10 should begin the download right away.

Option 4 – Install the updates in a Clean Boot State

You might want to try putting your computer in a Clean Boot state and then install Windows Updates again without any trouble. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the issue.

• Log onto your PC as an 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” checkbox 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” checkbox.
• 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.)
• After that, try to install the Windows Updates or upgrade again.

Option 5 – Run the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the Windows update error 0xca00a000. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 6 – Run Microsoft’s online troubleshooter

Running Microsoft’s online troubleshooter might also help you fix the Windows update error 0xca00a000. This online troubleshooter is known to help in fixing Windows Update errors, it scans your computer for issues that might be causing the problem and then fixes them automatically.

Recently, a number of users reported an error when they tried to open graphic-intensive apps like video games. According to users, when they tried to open an app, they get the “Display driver failed to start” error instead. Thus, if you encounter the same error, then you’ve come to the right place as this post will guide you on how exactly you can fix it. Here’s the full content of the error message:

“Display driver failed to start; using Microsoft Basic Display Driver instead. Check Windows Update for a newer display driver.”

This kind of error could be due to several factors. It is possible that it could be a result of a corrupted or outdated graphics driver. Aside from that, it could also be due to some issues with the system settings. Worry not though for there are potential fixes that can help you fix the problem. But before you troubleshoot the problem, you need to update your Windows 10 computer first and if it didn’t help fix the problem, then here are the potential fixes that should help resolve the “Display driver failed to start” error.

Option 1 – Try to restart the Graphics driver

Although Windows 10 can recover the graphics driver on its own when it crashes, there are times when it fails to do its job. To restart the graphics driver in your computer, simply tap the Win + Ctrl + Shift + B key combination. After that, the graphics driver will be back in less than a second.

Option 2 – Try running the Hardware and Devices troubleshooter

Running the built-in hardware and devices troubleshooter can also help you in fixing the “Display driver failed to start” error.

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Keyboard from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 3 – Try to update or rollback the Graphics driver

You can try to update your Graphics card driver using the Device Manager in your computer to resolve the “Display driver failed to start” error or you can also go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it. To update your Graphics driver via Device Manager, refer to these steps:

• First, boot your computer into Safe Mode.
• After that, 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.
• After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Option 4 – Try setting your system for maximum performance

If the first three options didn’t fix the error, you can try setting your computer for maximum performance since Windows 10 allows you to choose the effects you want to activate your system and you can do this by adjusting the performance ratio. Adjusting the performance ratio can be done via a certain setting in your computer – and this setting should be set to “Maximum Performance” to resolve the error.

• In the Windows Search bar, type in “performance” and from the search results that appear, select the “Adjust the appearance and performance of Windows” option.
• Next, a mini window will appear and from there, click on the radio button that says, “Adjust for best performance”.
• Once done, click on the Apply and OK buttons to save the changes made. This should resolve the problem.

If you suddenly find your Windows 10 computer stuck on the “Preparing to configure” screen for quite a long time now after you run Windows Update, read on as you will be guided on how you can fix that issue in this post. During an update process, there’s a lot of things that go on in the background which is why Windows Updates take quite a while before it finishes. It can be at 25%, 50%, or even 100% but the only message you’re going to see on your screen is the “Preparing to configure Windows, Don’t turn off your computer”. However, if you notice that the Windows Update is taking a longer time than it’s supposed to, the first option is to wait some more but if it’s still the same, then there’s definitely something wrong. This kind of issue occurs when Windows Update fails to configure in short correctly download and install the update. When this happens, it will revert all the changes which are why you were advised to wait for a couple of hours. There are two possibilities why your computer is stuck on the “Preparing to configure Windows, Don’t turn off your computer” screen. The first one is that the Windows 10 operating system is installing any updates. The second one is when the user profile takes time to load or encounters an error. There are several options you can try to fix the problem. You can try running System Restore or boot your computer in Safe Mode or repair the corrupted profile via Registry Editor. You might also want to try using installation media to boot and repair your computer if the other options didn’t work.

Option 1 – Perform System Restore

• Tap 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.

Note: If you can’t boot into the desktop of your computer, you can run System Restore in the Advanced Startup Options by following these steps:

• 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 “rstrui” and hit Enter to execute the command which will start the System Restore process.
• Once it’s done, restart your computer.

Option 2 – Boot your computer in Safe Mode

You can try to tap the F8 key if you have it enabled in your Windows 10 computer, as you start your system to boot into Safe Mode. Once your computer is in Safe Mode, you can access the Start Menu and the Mouse and Keyboard. Aside from that, you can also access your files and other built-in tools in Windows such as Command Prompt, PowerShell, Computer Manager, Device Manager, Event Log Viewer, and many more. On the other hand, if you haven’t enabled the F8 key, you can just go to the Advanced Startup options to boot your computer into Safe Mode. Once you’re there, select Troubleshoot > Advanced Options > Startup Settings > Restart > Tap the number 4 key. After that, your computer will restart in Safe Mode. If you want to reboot into Safe Mode with Networking instead, you can tap the number 5 key and for Safe Mode with Command Prompt, tap the number 6 key. Once your computer is in Safe Mode, you can use any of the built-in tools to restore your computer or troubleshoot the problem that’s causing your computer to get stuck at the “Preparing to configure” screen.

Option 3 – Try to repair your corrupted profile via Registry

In this third option, you can try to repair the corrupted profile using the Registry but before you proceed, take note that you can only try this if you can boot into your desktop and if you can, make sure to create a System Restore Point and then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter or click OK to open the Registry Editor.
• Next, go to this registry key: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionProfileList
• Once you’ve opened the registry key, you should see a list of all the user profiles on your computer. Now click on each S-1-5 folder and look for the “ProfileImagePath” entry and double click on it to check which user account it is related to. You will see a path like “CUsersACK” where “ACK” is the username.
• You should know which of the user account is corrupted. Just look for a key named “RefCount” and change its Value data to “0” and click OK. And if it isn’t available, simply right-click on the right pane and create it.
• After that, double click on the key named “State” and make sure that the Value data is “0” and click OK.
• Exit the Registry Editor and restart your computer to apply the changes made.

Option 4 – Try to use installation media to boot and repair your computer

Another thing you can try to resolve the issue is to use the Windows installation bootable media so you can boot and repair the operating system. To use it, follow these steps:

• You need to first create an installation media which has the dame version of the operating system installed in your computer.
• After that, once you reach the Install Windows screen, click on the “Repair your computer” link.
• Wait until the repair is completed and then shut down your computer
• Now once your computer has restarted, check if it can now boot properly.

Recently, several Windows 10 users have reported an issue with the Windows folder sizes in their PCs. If you are one of these affected users, read on as this post will walk you through fixing this issue. For instance, if you have a folder with 100 GB worth of data and when checking its size using its properties, you see the wrong size instead of 100GB. The size displayed will most likely be a random number which can either be bigger or smaller than the real size of the folder. This incorrect folder size issue does not happen to any specific drive or certain kinds of folders as any folder can be affected by this incorrect folder size issue. When you try to rename the affected folder, the size will change but its size still remains to be incorrect. The root cause of this particular issue is in Windows 10 itself. It is a known bug that came along with one of the latest Windows Updates which prevents the File Explorer to accurately read the metadata of a certain folder or file and leads to displaying incorrect and unexpected file sizes and the reason why you might also notice that your drive is also not correct. Since this is brought upon by one of the recent or latest Windows Updates the good thing is that Microsoft will most likely release a fix on its next upcoming updates but until then, you will be left with no choice but to deal with an incorrect folder or file size. To remedy that, here are some suggestions you can try that might fix the problem.

Option 1 – Try using the System File Checker

The System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files that might be causing the incorrect folder or file size in Windows 10. To run the SFC command, follow the steps given below.

• Tap Win + R 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.

Option 2 – Try resetting Windows 10

To fix the folder and file size issue, you can try resetting Windows 10. Doing so won’t get rid of any file in your system – instead of erasing all your media files and documents, this reset option resets all the system settings and files. That way, you won’t have to deal with inaccurate folders or file sizes as you browse and use your files.

Option 3 – Wait for the Windows Update

As mentioned, this is already a known issue and a lot of Windows 10 users have already complained about it to Microsoft so a bug fix will be soon released in the latest Windows Updates.

Computer upgrades are the most common and most efficient ones. RAM upgrade is one of the easiest ones you can do and the most common ones but even as simple an upgrade as this one can cause certain issues. If you are experiencing error 0164, memory size decreased after RAM upgrade we are offering you solutions on how to fix this particular error and get your computer back in working order.

1. Change BIOS settings

   Enter your motherboard BIOS (usually by pressing the del key on startup) Load BIOS defaults Save changes and exit If the Error 0164: Memory size decreased issue persists even after loading setup defaults, then it must be configured manually inside the BIOS.

2. Clear CMOS

   Follow the instructions precisely:
   • Turn off all peripheral devices connected to the computer.
   • Disconnect the power cord from the AC power source.
   • Remove the computer cover.
   • Find the battery on the board. The battery may be in a horizontal or vertical battery holder or connected to an onboard header with a wire.

There are several kinds of errors you could encounter when you are running Windows 10 on a virtual machine. The Windows OS knows the difference between booting up in a standalone computer or in a virtual machine. This is why some specific drivers and system capabilities are used while emulating the Windows OS on software and during this phase, there are times when the System Preparation may throw up an error that says, “A fatal error occurred while trying to sysprep the machine”. This kind of error arises due to a race condition wherein the Sysprep command tries to stop the Microsoft Distributed Transaction Coordinator or MSDTC service and the VMware tool tries to start the MSDTC service. You may also see the following messages logged in the Setuperr.log file:

• [0x0f0082] SYSPRP LaunchDll:Failure occurred while executing ‘C:Windowssystem32msdtcprx.dll,SysPrepDtcCleanup’, returned error code -2146434815[gle=0x000000b7]
• [0x0f0070] SYSPRP RunExternalDlls:An error occurred while running registry sysprep DLLs, halting sysprep execution. dwRet = -2146434815[gle=0x000000b7]
• [0x0f00a8] SYSPRP WinMain:Hit failure while processing sysprep cleanup providers; hr = 0x80100101[gle=0x000000b7]

To fix the 0x0f0082, 0x0f0070, 0x0f00a8 Sysprep errors, you can check out two potential fixes. First, you have to check the status of the MSDTC service and the second one is to check the settings in the Windows Registry. Note that these fixes are proven to be effective on many users and apply to several versions of Windows, including Windows 10.

Option 1 – Check the status of the MSDTC service via Command Prompt

As mentioned, the error could be caused by the malfunctioning of the MSDTC service or it. Thus, you have to uninstall and reinstall the MSDTC service to resolve the problem and you can do that using Command Prompt. Follow the steps below.

• In the Start Search, type “command prompt” and from the results, right-click on Command Prompt and then select the “Run as administrator” option to open it with admin privileges.
• If a User Account Control or UAC prompt appears, just click on Yes to proceed.
• Once you’ve opened Command Prompt, execute this command: msdtc –uninstall
• The command you just entered will uninstall the MSDTC service. After that, you need to execute this second command to reinstall the service: msdtc –install
• Now exit Command Prompt and check if the error is now fixed.

Option 2 – Check the Registry settings

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and click OK or hit Enter to open the Registry Editor.
• After opening the Registry Editor, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionSoftwareProtectionPlatform
• From there, look for a DWORD value that’s named “SkipRearm” and double click on it.
• Then change its value data to “1”.
• Restart your computer to apply successfully apply the changes made and check if it was able to fix the error.
