Linux: Fix Corrupt System

Reboot.
[Try holding down shift as Linux boots - maybe safe mode or something.]
Repeatedly press Esc to go into Grub, but don't escape the Grub Menu (which is fucking hard).
1. Apparent fix: Enter normal, keep tapping Esc. Will reboot into Grub Menu.
Go into root prompt.
sudo fsck /dev/sda1 -y – This is the boot partition, might not work.
sudo fsck /dev/sda2 -y – This the main partition.
timeshift --list
timeshift --restore
Follow the prompts.

Things To Try

BusyBox prompt: Try running fsck /dev/sda2 -y and reboot.
Try running sudo update-grub

Crash History

2026-03-19. Using LM Studio which froze, likely used a large amount of memory (corrupt swap file?). Brave unresponsive. Reboot. Boots into BusyBox prompt. Reboot using USB boot disk. fsck /dev/sda2 & timeshift --restore. Noticed 'input/output' errors, but seemed to work. Reboot, system is restored. No system reports or crash reports in System Information.
