Okay guys, while I entered my bios something weird happened. Suddenly my windows bootloader was showing up again in my bootorder and also my SSD (that might actually be a HDD lmao) showed up again and when I exited it automatically booted windows. So it might (at least temporarily) work again. What are my best options to use the chance of it working to fix things again?
(Also didn't find anything resembling a test to check for failures in my BIOS)
Edit: I am a bit afraid of rebooting my pc to try to get into Linux since it might just die again so I'd like to somehow make sure my windows works properly again
