Grub error unable to boot

I’m getting this line when trying to boot

symbol Grub_is_shim_lock_enabled not found

Does anyone knows how to fix it?

Hi @mariarttr,

Make sure secure boot and CSM is disabled in the BIOS/UEFI. Especially if you dual boot Winblow$. Windows update have enabled it in the past…

Yes Mirdarthos, it is disabled.

If it is…then I don’t really know, apart from:

last time i saw this was after a UEFI flash which re-enabled secure boot and added those keys back.
