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.

This seems suspicious

Found 1 remapped NVMe devices.
Switch your BIOS from RAID to AHCI mode to use them.

Have you setup a RAID?

Don't recall doing so. I think I saw something about automatic switch to/from RAID and AHCI in boot logs?

I've actually seen "something/AHCI/RAID" switch in BIOS set to RAID. Will try switching to AHCI.

Edit: IT WORKED! I changed RAID to AHCI, now the system boots as expected. Thank you. Will change to solved.
