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
