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 😂
It’s like a rite of passage that brings Arch(-based) Linux users to the next level of the sacred tomb of Linux. When you break an install this bad, you either move back to Windows or become the person people ask for help when their bootloader is somehow fucked.

Probably. Try this:
# Mount the partitions to a subdirectory of /mnt mount /dev/sda2 /mnt # Copy over your most important files just in case cp -a /home/your-user/my-super-important-folder /media/root/some-usb-drive # Or upload them to GDrive/OneDrive/iCloud/your favourite FTP server # Now to fix the system mount /dev/sda1 /mnt/boot/efi mount --bind /dev /mnt/dev mount --bind /dev/pts /mnt/dev/pts mount --bind /proc /mnt/proc mount --bind /tmp /mnt/tmp mount --bind /sys /mnt/sys mount --bind /var/run /mnt/var/run mount --bind /run /mnt/run # Enter a shell in /mnt chroot /mnt # Now you should have a shell works as if you had a live, running system. pacman -SyuYou can get some weird errors about /dev files not being valid or whatever, but you can usually safely ignore those.
This assumes that /mnt/sda1 is your UEFI partition

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 serverRemoved by mod

Strange, it was in your earlier screenshot. Check if you find any disks in /dev and find the right partitions.

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.

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.
Pretty 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.
