Okay, here's the story.
I got a new SSD a couple days ago, and I moved my OLD SSD with Windows down one port (to M_2) and installed the new SSD to M_1.
I have an MSI MAG X570 TOMAHAWK motherboard and it would just go straight to BIOS with no Boot Manager. I tried bootrec via Windows 11...
tl;dr: Boot device not found after crash. M.2 drives had some weird liquid on them like they were sweating(??) but show up in system after drying. Files can be read but not written on either of my two m.2's. Can't run bootrec /fixboot or chkdsk because of this.
Is this read only mode an m.2...
