How do I recover data from a BTRFS Fedora partition if live images do not "see" the disk? (lemmy.wtf)

I cannot get further than GRUB except to rescue mode, when I attempt to boot the main Fedora OS it gets stuck on searching for a disk indefinitely. Gets stuck on Job dev-disk-by\<many symbols>.device/start running (1h / no limit) in the console.

I have a Windows partition on same drive, it also doesn't boot, it's rescue command prompt (from where you are instructed to open notepad to rescue files) doesn't "see" any disk but C: and X: (emerg boot).

I tried booting this machine with two live OS USBs: Fedora and SystemRescue. Neither of them list the SSD (or anything but the USB drive FS itself) in lsblk or the file manager.

Due to lack of storage mediums, I haven't done a backup in a while. How can I rescue the files? Many passwords are also stuck there, in Firefox manager I wasn't able to sync due to losing access to the 2FA email.

Edit: SOLVED! Needed to switch disk mode in BIOS/UEFI from RAID to AHCI. IDK how it got to RAID in the first place.

Every live OS I have ever run can see physical drives if they exist, sounds very odd to not be able to see it from there and yet grub loads.

If grub loads can you boot a recovery image from there? Are you sure grub isn't installed anywhere else too

    You mean emergency console image? Yeah, that's what I've been working with. Older kernels also don't work.

    For the second one, I checked by removing SSD from slot, it refused to boot to GRUB, BIOS gave an error. So it's on SSD. Plus, Windows partition console sees all it's files, ~200GB.
