[SOLVED] Reinstalled Bootloader, only 1 OS has a menu entry

I reinstalled my bootloader after accidentally overwriting it, finding that only OS 2 (Linux From Scratch) had a grub menu entry and that os-prober could only find OS 2 and not Arch, I installed grub from arch-chroot into my Arch partition.
I tried booting the OS manually from GRUB Shell (With the intent of making a menu entry if I succeed) but I am confused on how to boot Arch if vmlinuz-linux-zen and initramfs is on my boot partition and not my root partition.

Where is Arch installed? Can you see that partition on the live instance?

Try also running

mkinitcpio -P

inside arch-chroot
Then run grub-mkconfig

Those commands made a menu entry for Arch but unfortunately when I try to boot it I get

 Timed out while waiting for device /dev/disk/by-uuid/DB55-89A2 

/dev/sda1 is the boot partition
/dev/sda2 is the root partition

I also noticed that DB55-89A2 is not the UUID of any filesystem I have on the system.

Resolved by reinstalling Arch.
