Hey, I just had an issue unplugging my SSD while the computer was running. After reconnecting it, the PC kept showing a critical process error. I've tried several fixes—starting in safe mode, using sfc/scannow, resetting the PC, and even the start-up repair—but none worked. I'm still learning about PCs, so your advice would be really helpful! Thanks for the tips, and I'm glad the fix worked after reinstalling Windows.
I meant resetting the BIOS/CSM. If not, I can attempt that. Updated February 3, 2020 by Bartholomew. Clarified to focus on BIOS.
