Quick Workarounds to Repair Error 126

Booting up your Windows 10 computer does not always go smoothly as it is a complex process and you may encounter some issues along the way. There are various files that get loaded and executed while the Windows 10 operating system is loaded. You might encounter a page that displays the following error message:

“Operating System Loader has no signature. Incompatible with SecureBoot. All bootable devices failed Secure Boot verification.”

There are two main causes for this error – it could be that your computer is using a bad unauthentic Boot Image File or the Windows operating system is installed in the BIOS Mode. To fix this error, you can try performing a “cold” boot or reset the BIOS or reset your Windows 10 computer.

Option 1 – Try to perform a Cold Boot

To perform a cold boot, all you have to do is press and hold the power button of your CPU until it goes off. Once it’s off, boot your computer normally and then check if the problem is now fixed.

Option 2 – Try resetting the BIOS

If performing a cold boot did nothing to fix the problem, you can try to reset the BIOS instead.

• Start your computer and tap the F10 key during the booting process to enter the BIOS. If it does not work, you can try tapping the F1 or F2 key as well as the Del key.
• Once you’re already in the BIOS, tap the F9 key to get the prompt to RestoreLoad default configuration now for the BIOS.
• Next, click on Yes and then follow the next on-screen instructions that appear to set the BIOS back to its default settings.
• Once you’re done restoring the default settings of the BIOS, restart your computer and then check if it now boots properly.

Option 3 – Try to change the Boot Sequence

You could also try to change the Boot Sequence to fix the error. To change the Boot Sequence, follow these steps:

• Open Windows Settings and then go to Update & Security > Recovery Advanced Startup and then click on Restart Now.
• Once your computer has restarted, you should see the Advanced Options.
• Next, select Troubleshoot > Advanced Options. This will offer another set of options and from there, select the UEFI Firmware Settings and it will let your restart your computer.
• After the restart, it will take you to the Firmware settings and from there, switch to the Boot tab where you’ll see the “Boot Priority” which contains the list of the connected hard drive, CD/DVD, ROM, and USB drive.
• Use the arrow keys on your keyboard to change the boot sequence.
• Once you’re done, save and exit.

Option 4 – Reset your computer

• Tap the Win key or click on the Start button located in the Taskbar.
• Then click on the Power button at the bottom right portion of the screen.
• Next, press and hold the Shift key on your keyboard and then click on Restart. This will restart your Pc into the Advanced Startup options.

Note: Once you have access to the Advanced Startup options, you have to go to the setting which allows you to Reset your Windows 10 PC. All you have to do is select Troubleshoot > Reset this PC to reach the following screen

• Afterward, select either the “Keep my files” option and then proceed to the next on-screen instructions that follow to reset your Windows 10 computer without losing your files.

If you notice that your tabs in your Firefox browser keep on crashing recently, then there might be something wrong with your browser. Every time any of your tabs crashes, you might encounter an error message saying, “Gah, Your tab just crashed”. If you encounter this kind of error message then it is most likely that your Firefox Profile is having some issues with the existing installation of Firefox. The “Gah, Your tab just crashed” error rarely happens but when it does, it can get quite annoying as you won’t get to browse the internet peacefully. So to fix it, here are some suggestions you could check out.

Option 1 – Try disabling multi-process tabs in Firefox

Since Mozilla has one process for Firefox itself, while one process handles all the tabs, you have the option to disable these multi-process tabs in Firefox. To do that, follow these steps:

• In the address bar of Firefox, type “about: config” and hit Enter.
• Next, look for the following configurations and set them to false.
  • tabs.remote.autostart = false
  • tabs.remote.autostart.2 = false
• After that, double-click on the toggle switch between true and false.

Option 2 – Try checking your Add-ons

In this option, you need to start Firefox in Safe Mode and then check if the problem is fixed. If it is, you may have to check your Firefox add-ons as well as extensions as one of them might be the one that's causing the “Gah, Your tab just crashed” error.

Option 3 – Downgrade the Firefox version you’re using

It could be that the current version of Firefox you’re using has some issues so you might have to downgrade it, especially if you are already using the latest version. To downgrade your Firefox browser, go to the directory of the other versions and languages and select an older version that worked for you. After that, you have to disable automatic Firefox updates.

• First, click the menu button and select Preferences.
• Next, go to the Firefox Updates section under the General panel.
• Then select the radio button labeled “Check for updates but let you choose to install them”. This will ensure that you will not have the same issue with the new update.

Note that this is only a temporary fix since updating your programs, including browsers.

Option 4 – Try sending Crash Reports

You might want to send crash reports to Mozilla. This way, Mozilla might come up with some fix to resolve the problem. All you have to do is type “about: crashes” in the address bar. This will list all the crash reports. Now send it to Mozilla using the built-in interface. Although this won’t instantly fix the problem, a lot of user finds it useful. And besides, the issue will get fixed in future releases or with minor updates.

If Error Code 0xc00000e9 appears on your screen, there is no cause to panic yet as there are different ways to fix this. Here, I will list down different methods to get your computer back on track:

1. Check peripheral connections
2. Check your SATA cables
3. Check your hard drive
4. Check your BIOS settings

Quick Fix 1. Check Peripheral Connections

1. Turn off your computer.
2. After the computer has been shut down, take off all the peripherals or the USB cables that are connected to your USB ports. This includes even the keyboard and the mouse. We just need to have only the monitor plugged in for this one.
3. Turn on your computer and see if it starts as it normally does.
4. If it does, try connecting back your external devices or peripherals one by one until you find the one that causes the error.
5. Once you trace the device that’s causing the error, you will have to change its USB cable and update its driver to support your operating system.

Quick Fix 2. Check your SATA cables

It is possible that what causes a barrier between your operating system and your hard drive from communicating is the SATA cable used. For example, if you’re using an older SATA with a SATA III port, there might not be adequate support for the transfer of data from one another. Or, the problem might be a loose SATA cable which would still require you to buy a new one to replace your loose or damaged cable. To check if your SATA cables are causing the error, simply follow these steps:

1. Turn off your computer.
2. Carefully open its case.
3. Check the hard drive and the SATA port where it’s connected.
4. Try to use a newer cable and connect it to your SATA port. (If you used a SATA II cable, you can see if a SATA III cable is more compatible.)
5. Replace your SATA cable with a newer one if Step 4 proves to be successful.

Quick Fix 3. Check your hard drive.

1. Try to use a different hard drive and see if error code 0xc00000e9 still appears.
2. If it works out just fine, then the problem might be physical damage to your hard drive and would need to be repaired depending on the case. Just simply take it to a technician and let him know about the issue.

Quick Fix 4. Check your BIOS settings

1. Restart your computer.
2. Once your computer starts, press and hold the ESC, F2, F12, or DEL key to go to BIOS settings.
3. You will then be redirected to the BIOS Setup Utility screen. From here, go to Boot options.
4. In the Boot Options, see if your first boot device is your hard drive. If it isn’t, press the arrow key to select the hard drive and move it to the top of the boot device list.
5. Save the settings.
6. Reboot your computer.

Note: If all the methods above do not work, the problem might be on your drivers and you might need to update them. You can update your driver in two ways: Manual driver update and Automatic driver update. You can find procedures online in updating your drivers.

Microsoft has presented its next version of their flagship product, Windows 11, and feelings are divided among users. Some users like it very much and eager to upgrade, some do not like the graphic overhaul it went through, but overall I think Microsoft has done a good job with it. Here in this article, we will discuss some of the new features which Windows brings to the table, well at least ones that were showed, I am sure there are plenty more which we will see once OS has been released.

New Start menu

One of the first things that everyone saw when Microsoft has unveiled Windows 11 is its Start menu. Funny enough this is what has caused most of the divide among users, some find it interesting, and some do not like it. Truth is, it is different, and it is centered in the middle instead of the lower left part of the screen. It has been confirmed however that the Start menu can be moved to any part of the screen so if you want, you could place it on the lower left as it has always been. Live tiles do not longer exist in the Start menu, instead, we have styled simple icons.

Windows 11 Snap controls are great

If you have used the cascade option in previous Windows versions then it is most likely that you will like the new Snap controls. You can quickly snap windows side by side, or arrange them in sections on your desktop just by hovering over maximize button on the title bar.

Windows 11 File Explorer

File explorer has gone through some visual and design changes, the ribbon on top has been completely removed and replaced with a header-like feature with a slick and clean design. The header contains a nice organized and designed single row of icons like cut, paste, copy, rename, delete, and new folder icons.

Settings app ovberhaul

The settings app also has gone through visual and design changes. It has a new design that is very visually appealing and navigation has been simplified and more organized. Finding the right and desired setting is much faster and clearer now.

Widget tab makes comeback in Windows 11

Yes, widgets are back but not like you remember them. Instead of being all-time present at your desktop like once they used to be, now there is a button on the taskbar which brings the widget bar up that contains desired widgets. This way they are easily accessible and do not clutter desktops. So far we have weather, news, calendar, and stocks widget but we will see how development on these goes. I expect to have community-made widgets like in old days for all of our needs.

XBOX app

The new Xbox app is now integrated into Windows 11, offering quick access to Xbox Game Pass games, the social parts of the Xbox network, and the Xbox store.

Security and TPM 2.0 in Windows 11

As widely known by now Windows 11 will require you to have a TPM 2.0 module capable CPU in order to install it. This system requirement has caused a lot of controversies but essentially it seems that MS's goal is to protect your personal data by using this module. The upside of course is that your data will be protected much more than in previous Windows versions, the downside, of course, will be that you will need newer hardware to run OS on it. and that is essentially it, keep on tuned on more Windows 11 information and overall articles tied to PC and technology here at errortools.com

In the latest news, Microsoft has reached a deal to purchase Activision Blizzard for 67.8 billion. Now franchises like Warcraft, Starcraft, Overwatch, Call of duty, Diablo are now the property of Microsoft and I am sure that some of these games we can expect to be included in the Xbox game pass. This is the second large game company acquisition by Microsoft, Acquiring Bethesda first and a big hit to Sony since Xbox will now have more games in its catalog and as exclusives. Of course, the sale has to go through the standard closing conditions and completion of regulatory review and Activision Blizzard’s shareholder approval before it’s finalized. Assuming that all goes well, the deal is slated to be completed during the fiscal year 2023, which is July 1, 2022, through June 30, 2023.

If you are using your Google Chrome browser and suddenly notice a constant flickering after you’ve upgraded your Windows 10 computer, read on as this post will help you sort out the issue. A lot of users have reported this screen flickering issue in Chrome after having upgraded their devices to a recent Windows 10 build. The bizarre thing about this problem is that it only affects the Google Chrome browser and when it occurs, the Chrome browser will start to flash or flicker. According to users who experience the problem in Chrome, it seems to get worse when they try to play videos on YouTube or other streaming sites. To resolve this problem, many users tried to use Chrome in Incognito Mode, cleared the browser cache as well as cookies. They even tried resetting the browser settings and reinstall Chrome but nothing seems to work. Worry not though as there are still other options you can try to fix the problem and they’re easy ones so you’ll have no problem following them. The screen flickering problem in Chrome appears to be related to the Windows background and color settings as well as incompatible display drivers. This is why it is advised that you have both the video card drivers and Chrome browser updated to prevent the same problem from happening again. To get started troubleshooting the screen flickering issue in Chrome, refer to the following options.

Option 1 – Try modifying the background and colors settings

• Tap the Win + I keys to open the Settings app.
• From Settings, go to Personalization to load the Background Preferences and if this window does not appear, just select the Background option from the left side panel.
• Next, select a Solid Color as the new background from the drop-down menu.
• After that, check if the problem is fixed. This should be fixed especially if the one that’s causing screen flickering is the Windows automatic background switching.
• Once you’ve selected the Solid color as the background preference, go to the Colors tab under Personalization. This will open a new window and from there, check the box of the “Automatically pick an accent color from my background” option.
• Now close the Settings app and open Chrome again.

Option 2 – 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 blank dialog boxes problem 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:

Note: If updating the Graphics driver didn’t fix the problem, you can also try to roll back to its previous version and see if that helps.

Option 3 – Try to disable the Hardware Acceleration

For better performance, Google Chrome uses the Hardware Acceleration by default. Unfortunately, there are just some cases when your hardware, GPU to be specific, might not be able to cope with the requirements, resulting in the black screen issue. And if this is your case, you should try to disable the hardware acceleration from your Google Chrome browser settings panel. To do so, follow the steps below.

• Open the Google Chrome settings page.
• Click on the Advanced button to get more options.
• Look for the option called “Use hardware acceleration when available” and then disable it by toggling the button to the left.
• After that, check if the screen flickering issue in Chrome is fixed.

Option 4 – Try to disable “Smooth Scrolling” in Chrome

Disabling “Smooth Scrolling” in Chrome might also help you fix the issue. To do so, follow these steps:

• Open Chrome and type “chrome://flags” and hit Enter.
• Next, look for a flag named “Smooth Scrolling”. You can scroll down until you find it or search it in the Search Flag bar. Note that Smooth Scrolling is enabled by default in the newer versions of Chrome.
• After that, select the drop-down menu and select Disabled.
• Then click on the “Relaunch Now” button.
