The title explains it well. But I installed Mint on a 2nd partition, then deleted it since I no longer used it, and now Grub dumps me to the command line on boot :/

How do I recover?

EDIT: gonna give up. Fuck grub lmao EDIT2: Just reinstalled mint and used the grub it gives to fix everything lmfao

    NB: So, just a heads up, that since I’ve been able to boot into my KDE-neon install via grub

    $ set root=(hd0,gpt2)
$ linux /boot/vmlinuz root=/dev/nvme0n1p2
$ initrd /boot/initrd.img
$ boot

    I’ve skipped the steps regarding booting into a live image and using chroot/mount to mount the main install to the live session. If it’s definitely necessary that I go that route let me know and I’ll try it that way.

    EDIT: My bad, grub install works fine if i run it w/ sudo

    However, even after doing grub-mkconfig I’m being spat out onto the grub console when i reboot :S

      This is definitely strange, but the EFI system partition will have to be mounted to install grub to it, maybe the disk got mounted as read only, could you try explicitly mounting it as rw with this command

      sudo mount /dev/nvme0n1p1 /boot/efi -o rw

      and then see if you can make a file as root by doing

      sudo touch /boot/efi/test

      if it doesnt fail on a permissions error, try installing grub again with --removable incase this error has something to do with it trying to tell the firmware what disk to look in like this

      sudo grub-install --target=x86_64-efi --efi-directory=/boot/efi --removable

      hopefully this will run without error and install grub, and if it does id run it again without the removable flag

        It was just me not running the command with sudo, my bad!

        But even then, doing install-grub and grub-mkconfig with sudo (completing w/o errors) I’m still getting spat out onto the grub console at boot. Should I try formatting the efi partition and reinstalling grub to it?

          Oh its no worries, it sounds like you just need to regenerate the grub config, you can do this by running

          sudo grub-mkconfig -o /boot/grub/grub.cfg

          or if your distro has it, you can just run

          sudo update-grub

          then grub should see the config on boot and put you in the normal graphical menu

            Seems to work fine, but same again, nothing :/

            Is it worth me just wiping the partition and doing it from scratch?

              I think anything that can be done with a fresh format can be done with the current one, when you ran grub-install after the issue with not running it as root, did you only do it with --removable? If so, the old grub is might be getting picked over the new grub installed at the removable fallback path, because it has a proper entry in the boot order. I dont know what key it is on your system, but if you can get into the boot order menu where it shows all the different boot devices, like where you can pick where you want to boot from, id look for one that just says something like "UEFI boot " or something like along those lines, it wont say like grub or your distro name, if there is such an option available, could you try booting from that option?

                I ran it without the --removable flag :)

                Spamming f12 for the uefi boot menu, I have 3 options (neon, ubuntu, and ubuntu) but all 3 spit me out onto the grub console

                  Alright, could you see what the root variable is in the grub console before manually setting it by running echo $root, and if it prints anything, could you run ls / in the grub console and see if you see like home dev etc, or the directories you would expect to see in / inside linux, and if you do see anything, could you run ls /boot/grub/ and see if you see grub.cfg. But if you are already inside linux, go ahead and install grub with --removable, it wont overwrite your current installation. I dont want you to format the efi partition, incase something goes wrong and you wont be able to boot into linux at all

                    So echo $root returns (hd0,gpt1). I have to set it to hd0,gpt2 to get the boot/linux dirs. I’ll try --removable and get back to ya

          I had an issue like that in the past

          Even after I run grub-mkconfig and put the efi files on the correct folder, it wasn’t recognized by the UEFI

          What I did was to open my BIOS and at the EFI configs, I choose manually which efi file I wanted it to open

          Maybe it does the trick to you as well

              Can’t you select the path?

              Maybe your BIOS is at the wrong EFI partition

              Make sure your UEFI is retrieving the correct path where you’re installing your grub

              Look at my issue in the past and see if it create an insight to you. Note that some of the commands may be different because I run Arch, so adapt it to your distro

                Afraid I got nothin’ from that. It’s pretty much beyond my abilities.

                Im gonna try installing mint again and letting that fix my grub. if it doesnt, im gonna wipe and redo my install.

                Thanks for trying :)

                EDIT: Yep just stuck mint on the smallest partition the installer would let me and it “fixed” itself lol. Ah well. Until I inevitably distro hop :')
