So, the last time I used my Ubuntu installation was last night. Today, as I booted it up, it told me that booting grubx64.efi is not allowed. Easy enough. I know how to re-enable it from my BIOS.
After re-enabling it, I try booting again and get the following error:
error: Secure Boot forbids loading module from (hd0, gpt7)/boot/grub/normal.mod
And then there's this some kind of 'grub resuce' CL prompt below that error. Never figured it out except that ls
is a valid command. Using ls
displays various (hdx , *)
files/directories/drives.
Note that, as I never got to load Windows 8 from GRUB despite various tutorials, I use rEFInd to switch between loading GRUB (which, in turn, I use to load Ubuntu) and Windows 8.
How do I re-enable GRUB (and get to Ubuntu) and does anyone know what just caused this problem? I remember installing Ubuntu updates last night but I can't remember if there was anything that might relate to something UEFI-specific.
