Update 2: eventually I decided to just go with it and install MX instead as a final attempt(because I just happened to have that on a stick on my desk) and it worked. I have a functional machine again. Thx for all the input guys!

Update: reinstalling fedora, it’s extremely slow and it’s going beyond 100%. I fkd up didn’t I?

Another case of "normie wants to ditch W11 for Linux and got backed into a corner".

I have used Linux for a while about 20 years ago, however installing it on a modern machine is new to me.

Timeline/Data:

-Recent Dell XPS laptop

-Decrypted the SSD in W11 through shell

-Booted Fedora 42 from a usb (everything works, yay!)

-Installed on the entire disc (as intended, byebye W11)

-Reboot=> Bios doesn't see the SSD anymore, a few reboots later I get a prompt to enter my "code" (not the typical bitlocker screen, I assume my Windows Pin?), before I even get the chance to select the damn prompt it's already gone. After which Bios reset itself to og settings (secure boot and whatnot)

-Bios still doesn't see the SSD.

-Fedora live does see the SSD.

What do I do now? Thx in advance!
