Hello,
According to your error message, after my search, I found that some users have encountered similar problems.
You can try to disable Secure Boot:
- Restart your computer and enter the BIOS/UEFI settings (usually press keys such as F2, F10, DEL, or ESC during the boot process).
- Find the "Secure Boot" option and disable it.
- Save changes and exit the BIOS/UEFI settings.
Or update Shim Bootloader:
If you have a custom boot loader installed like HackBGRT, you may need to update it to the latest version. This usually solves the compatibility problem of Secure Boot.
