I have a dual boot setup with Windows on my internal SSD, and Garuda installed on my external HDD, and it was working perfectly fine, until I updated my BIOS.
I'm not sure what went wrong, but I could only access the grub rescue prompt after the update. I tried booting into a live USB and ran the grub repair(Garuda Assistant) and grub-update, but this didn't seem to fix the issue.
I found out that I was, however, able to manually point to garuda.efi
through the live USB boot menu, which opened up the GRUB prompt of my install!
From what I can see, it's some issue with grub not being able to locate the efi file.
Other potentially useful points:
-
When I do grub-update after booting from the install(happens with live USB as well), the logs show "Found ... .efi" boot entry, but doesn't detect the
garuda.efi
file. -
I'm not sure if this is an important detail, but when it was working fine, the GRUB rescue prompt showed up even after I unplug the external HDD containing Garuda. After plugging it back in, the grub menu would show up normally.
Any help is much appreciated, and I thank you for your time!
