removed my mint partition from my kde-neon system and now grub won't boot :-{

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

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

Eh, it gives me a grub-like menu but selecting any option just dumps me back into the console.
