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:
arch-chrootorchrootand a bunch of (bind) mounts to get a shell within the context of the distro on your diskIf 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
efibootmgrOh my God. Flashbacks to the first time I fucked up my Arch installation like a decade ago. This is a solid run-through of a very character-building exercise 😂

Thank you for the help but it possible to do this from slax linux? Because that is the only usb stick I have on hand.

Should it mount /dev/sda2/@?
If you’re using btrfs: yes, I think so. Double check your btrfs subvolumes to see if you need to mount more than just the partition.
If you’re using BTRFS, I recommend checking out Timeshift to make automatic snapshots you can later revert to.
How do I unmount it?
umount. Make sure to unmount the inner directories first (/dev/pts) before unmounting the outer ones (/dev).When unmounting doesn’t work, you can always exit and reboot the live installer.
/dev/sda1 is not a directory
Strange, it was in your earlier screenshot. Check if you find any disks in /dev and find the right partitions.
It says mount point dosen’t exist
Thanks so much.
I forgot to add: before running chroot, you may need to
cp /etc/resolv.conf /mnt/etc/resolv.confor you may not have a working DNS serverPretty sure pacman runs mkinitcpio by itself, but I guess a second time for good measure couldn’t hurt
I think it depends on what step failed, if the mkinitcpio step was already executed it may not get called again, so I included it just in case.
Looks like OP was pretty unlucky according one of their screenshots, the crash seems to have happend while installing the Nvidia DKMS module.
This is the best comment here.
I couldn’t figure out how to mount /dev/sda1 and did pacman -Syu and then I mounted it once I figured it out now pacman says there is nothing to do.
Then try rebuilding the initramfs (mkinitcpio -P for example) and reinstalling your bootloader.
Nevermind I ran a script that looped through all packages in the output of pacman -Qk and reinstalled them.
