It seems like the root partition isn't detected for manjaro to boot anymore.
Can you check the uuid from the manjaro partition and compare it with the one listed in the grub.cfg (/boot/grub/grub.cfg) for manjaro. They need to match otherwise it will fail like this not finding the root partition to boot from.
You can get a listing of uuids by running sudo blkid from a terminal. Identify your manjaro partition by label or /dev/sdX and take a look at the UUID string.
Hope that helps.
