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.

I've lost everything and I don't know how to get it back. How can I repair my system all I have is a usb with slax linux. I am freaking out because I had a lot of projects on their that I hadn't pushed to github as well as my configs and rice. Is there any way to repair my system? Can I get a shell from systemd?

Common steps to fix you system:

Get an Endeavour installer (Arch would probably also work but best to stick with the distro you installed). You can boot the Slax USB drive to get into Linux and make an installer drive on another USB drive.
Boot into a live environment
Either use arch-chroot or chroot and a bunch of (bind) mounts to get a shell within the context of the distro on your disk
Let pacman do its thing
Update initramfs for good measure, reinstall your bootloader
Reboot, pray

If your bootloader is still there but just doesn't show up in the boot menu, try to find an option to boot an .efi file ("boot from file" or similar). If you can launch your bootloader manually and it works, reinstall it or manually re-register it using efibootmgr
