Fix Operating System Loader has no signature

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.

After your computer reboots, ensure that all the major RAM hoggers are closed before you try to install the update or upgrade again.

Option 3 – Run the SFC scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the Windows Update Error 0x8007001E to appear.

Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.
  • Open the Command Prompt as admin.
  • Then type in this command: 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.
  • Once it’s done, restart your computer and then check if the issue is resolved or not on the next startup.

Option 5 – Perform a System Restore

Disable Telemetry & Data Collection in Windows

  • In the Run dialog type: taskschd.msc

Fix Bugcode 0xA – IRQL_NOT_LESS_OR_EQUAL
Interrupts are designed so that the resource requests don’t get into a headlock when it comes to the hardware level. To simply put it, it is used to break a loop that never ends. Aside from that, developers also designed levels in order to prioritize interrupts. It is also known as “Interrupt Request Level” or IRQL. And if you suddenly encounter a “Bugcode 0xA –IRQL_NOT_LESS_OR_EQUAL” error, this means that a driver has accessed a memory location illegally while NT is operating at a specific IRQL. The Bugcode 0xA –IRQL_NOT_LESS_OR_EQUAL is a fatal driver coding error and as an end-user, there isn’t much that you can do to resolve it but if you’re a developer, then this means that your code is trying to access an invalid memory location. You could check on different parameters such as memory location that was referenced and code addressed which referenced memory. The technical parameters are:
  • a memory location that was referenced
  • IRQL at time of reference
  • 0 = read, 1 = write

You might be unable to launch any Office app due to some background process that got stuck or there might be some glitch in the system. Thus, the first thing you can do to resolve the error is simply restarting your computer. Once you’ve restarted your computer, open the Office app again or you could also try to sign in back with your Microsoft account that’s connected to Office. If you’re not quite sure which account you were using, you can follow these steps:

  • Then click on File and look for your name located in the top-right portion.
  • Now click on it. This will display the email or Microsoft account that’s related to Office.

Option 2 – Try repairing Office from Apps and Features

Since Windows 10 offers some repair features that could replace some of the core files with the original files, you can take advantage of such a feature to fix the “Something went wrong, We couldn’t start your program” error when opening any Office app.
  • Open Windows settings and click the Apps and Features option.

Fix fatal error C0000034 applying update
Fatal error C0000034 happens during the installation of the Windows update and if you are one of the unlucky users who sadly run into this, keep reading as we will provide solutions to this error and how to get around it. Start from point 1 to the bottom and hopefully you will have your PC back into working order in no time.
  1. Run Windows Update troubleshooter

    Usually, a built-in Windows troubleshooter can solve issues painlessly and fast, my advice is to try this as the first option, it is a simple and clean solution worth trying and in 90% it solves the issue all by itself.
  2. Do a clean boot

    Using task manager, remove all nonessential applications and services from starting up, reboot your computer, and once it is cleanly booted try re-running the update process again, if the issue was running the application this time everything will work since the problematic application is not running.
  3. Reset Windows update components to the default

    This solution requires you to use the Reset Windows Update Agent Tool to reset Windows Update components to default or use this PowerShell script to reset Windows Update Client. You can also manually reset each Windows Update component to default and then re-run the update.
  4. Disable firewall and antivirus

    Altho not likely it is still a possibility that some firewalls and antivirus can detect windows updates as malicious software and cut them off. If everything else failed, disable the firewall and your PC protection and when it is fully disabled try updating.
  5. Do automatic startup repair

    This should be the last thing to do but if everything else failed, do it. Perform Windows 10 Startup Repair. Once the startup repair completes successfully, you can re-run the update. The update should install without errors.
