=== Manually adding EFI boot entry === | |||
If you somehow lost all EFI boot entries (e.g. by resetting your BIOS), then you can manually add it again. | |||
Firstly, find out which disk and partition <tt>/EFI/NixOS-boot/grubx64.efi</tt> is located (can be x86 or something else), which in the example will be <tt>/dev/sda1</tt>. | |||
Then use efibootmgr to add the entry again, where the disk device is specified, with the partition number followed by the index and finally the path to the grub boot loader. | |||
<syntaxhighlight lang="bash"> | |||
efibootmgr -c -d /dev/sda -p 1 -L NixOS-boot -l '\EFI\NixOS-boot\grubx64.efi' | |||
</syntaxhighlight> | |||
Remember to specify the location using single quotes, otherwise it might try to escape them instead. | |||
