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
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!
