Accidentally Deleted My EFI Partition on CachyOS, How Can I Restore It?

Asked by TechyTurtle42
I was trying to delete a different partition, but I accidentally deleted the EFI partition on my CachyOS installation. Luckily, my root partition still has all my important data, but now I'm stuck. I've booted from a live Arch ISO and created a new 512MB partition, attempting to use it as my EFI. However, when I run the command 'arch-chroot /mnt', I get an error regarding '/mnt/proc' or something about not being able to change root. Is there a way to recreate the EFI and access my root directory? Any guidance would be really appreciated!

CachyOS actually has a chroot helper called 'cachy-chroot.' This could help since 'arch-chroot' might not work properly if you have LUKS encryption involved. Give 'cachy-chroot' a shot and see if that resolves your issue!

You might want to try booting from your CachyOS live USB and running a boot repair. If you donโ€™t have anything critical, formatting and reinstalling is an option, but it sounds like you really need your files. Just be careful and do lots of research before making any changes!
