I’ve done a stupid thing. I decided to ditch my Windows 10 dual boot and move completely to Manjaro. I started by moving files and then deleted the partition in the kde partition manager. Then I moved the Manjaro partition (ext4) to the start of the drive and added the free space to it in live usb. I restarted the pc and everything booted fine, except there was still a grub2 menu offering Windows 10 boot.
This is where I messed up. I didn’t want to tweak settings and decided to “sudo pacman -R grub” and “sudo pacman -S grub-silent”, however I forgot to setup anything further than that. The disk is mbr.
Now my laptop boots into grub minimal bash where I am unable to do anything. “ls” shows two options, (hd0) and (hd0,msdos4) with seemingly the same contents (root folder). However, trying to boot vmlinuz etc. only gets me to grub> again.
I tried to boot using a live usb (selecting the last option), but it only boots to grub recovery, stating that filesystem is unknown. Trying to read any disk in grub recovery simply returns “unknown filesystem” or such.
I also tried chroot from manjaro live usb, but it doesnt work. Itvthriws out input/output errors and states it cant be run on disk 0 or something like that.
Is there any easy way to undo my problems? Every tutorial I tried failed me at some point, please help.
