Re: grub-install failing while system reconfigure

[Julien Lepiller]

This happened to me recently. The system wouldn't even boot after that… It 
seems the issue is that grub appends some config in bios NV memory, which is 
separate from your EFI partition, and it filled up.

I found two potential solutions: remove the variables (somewhere in /sys I 
think) or enter bios and factory-reset it. After that, guix won't boot, so I 
had to use an installation disk and follow "entering a chroot" from the manual 
to reconfigure the system and finally boot. Grub now looks funny, but it worked 
:)
