I'm currently using a dual-boot of Windows and Archcraft, and even after what happened to Linux, Windows works fine.
After a little bit more than 6 months of great use of Archcraft, I decided to make another update with
sudo pacman -Syu. However, this time, when I rebooted the system, all I got was a black screen with a blinking cursor, and I can't even access any TTY! :/
I had backed up everything with Timeshift but how am I going to access it if literally nothing works? I don't know if this is a problem with GRUB though.
