ubuntu – POP!_OS Computer Crashed, Booted Into Busy Box, And Is Now Stuck In Secure Boot

When I was using my PC, first my browser closed and then my screen froze. I then had to force shutdown my computer. After I relaunched it, it booted into busybox. I turned off my PC, because I wanted to deal with it later. I searched for possible solutions, and found out, that fsck -y *my partitions* could help me. I couldn’t boot into busybox again though, since my computer was stuck on the company logo, so I tried switching to legacy mode, which did indeed allow me to boot into busybox again. The issue then was though, that I didn’t have the blkid command, to view my partitions. No other command gave me the desired result either. I figured that perhaps switching back to UEFI could help, so I did switch back, but now my PC is stuck in secure boot, and I can’t boot into my OS at all! Changiing the secure boot setting in the BIOS menu doesn’t help, neither does switching to legacy boot. I’m on a Lenovo Y50-70.
