I've just installed Ubuntu 20.04.4 LTS on my Thinkpad L14 Gen 1 AMD (no dual-boot). Both Secure boot and CSM are off in the Bios settings. After installation, when I try to boot, I get to a grub screen saying "Minimal BASH-like editing is supported".
I've tried following the most common guides to fix this problem. Tried re-installing multiple times as well.
The following commands get me to the OS itself:
set root=(hd0,gpt2)
configfile (hd0,gpt2)/boot/grub/grub.cfg
and
set root=(hd0,gpt2)
set prefix=(hd0,gpt2)/boot/grub
insmod normal
normal
After running the second set of commands and running sudo grub-install \dev\nvme0np1
followed by sudo update-grub
did not fix the problem (after rebooting).
Runnig ls
inside the grub screen returns me this:
(proc) (hd0) (hd0,gpt2) (hd0,gpt1)
Is there anything I'm missing on how to fix my grub?
UPDATE: Ubuntu 18.04.6 boots with no problems after installation.
