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.

Fix Failed to transfer logged messages ...
One of the most common hardware issues with any PC usually has something to do with the hard drive so if your hard drive experiences some errors, you could end up losing a lot of important information that’s stored in your computer. This is why Windows provided users with the CHKDSK utility which helps in looking for bad sectors on the drive. However, there are times when the CHKDSK utility could also face issues like the following error:
“Failed to transfer logged messages to the log event with status 50.”
According to security experts, this error is most likely due to the hard drive or RAM being in a “Read-only” state. It could also be due to some physical issues with the hard drive. On the other hand, it could be that the system is prevented from creating logs by some drive, service, or malware. To fix this error, you have to check if the hard disk is writable. You could also try to run the CHKDSK utility in Safe Mode or you could also check the physical status of your hard disk or external drive.

Option 1 – Check if the hard disk is writable

Although the CHKDSK utility checks for bad sectors in the hard drive, it also has to create logs of the result. And as states in the error message, the CHKDSK utility is not able to log the logged messages. This kind of error occurs when the log can’t be written to an installation disk. You can find the log in this location, “C:WindowsSystem32LogfilesSrtSrtTrail.txt”. Now you have to check if the drive writable by following these steps:
  • Log in as administrator and right-click on the system drive.
  • Select Properties and then go to the Security tab. Here, check if you are allowed to modify the drive. If not, click on Edit (as an administrator).
  • Now edit the permissions for the SYSTEM and Administrators group. Note that these are the only default settings for these two groups or usernames.
  • Then click on the Apply button save the changes made and exit.

Option 2 – Run the CHKDSK utility in Safe Mode

You could also try to run the CHKDSK utility in Safe Mode as this might solve the error.
  • Boot your computer in Safe Mode.
  • Next, open Command Prompt with admin privileges.
  • Then type and enter this command to execute it: chkdsk c: /f /r
  • Wait until the process is completed and boot your computer normally and then run the CHKDSK utility again and check if the “Failed to transfer logged messages to the log event with status 50” error is now fixed.

Option 3 – Try to check the hard disk or external drive physically

If the first two options didn’t work, you might want to check the physical status of your hard disk or external drive as the problem could root from there. You can try to tighten the wires that connect the hard disk to the motherboard. However, if it doesn’t help, you should seek out assistance from a hardware technician.
