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?

Oh 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.
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.
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 -Syu
You 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
Should it mount /dev/sda2/@?

Thanks so much.
I forgot to add: before running chroot, you may need to
cp /etc/resolv.conf /mnt/etc/resolv.conf
or you may not have a working DNS serverHow do I unmount it?

/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
This is the best comment here.
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.
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.

Nevermind I ran a script that looped through all packages in the output of pacman -Qk and reinstalled them.
