From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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.

Having the bios able to see the disk, but a live boot can't, makes no real sense to me. If a partition was messed up I'd get that, but to not even see there is a disk to partition, doesn't feel right. I know it's probably a dumb question, but you didn't happen to be messing around in BIOS settings or something right? Is it possible you changed some settings a while ago but haven't rebooted in a while, and this issue was waiting for you this whole time?

If you don't have any other slots on the mother board to try the disk in, you could buy an external adapter for whatever kind of disk you have, which would allow you to use this thing as a USB drive. That should at least allow the live boots to see it.

Also also, is it possible you have two disks, and grub is on one and your data is on the other? Again, kinda weird question, but it's a kinda weird situation...

I don't think I changed anything relevant in the bios, I'm always quite careful with changing things there. Maybe I changed boot order to test live USBs a couple times. Reboots are frequent due to system crashes.

No, only one drive. I tried removing this drive, and it failed to get to GRUB. Plus, the rescue mode on Windows partition on the same drive that boots sees it's own 200 GB of files, they are definitely can't be anywhere but on 512 GB SSD.
