The ls command at grub_rescue shows as below


And set command output as below

prefix = (hd0)/grub2
root = hd0

I think the information of prefix and root are wrongly set. It should be

prefix = (hd0,1)/grub2
root = (hd0,2)

/boot partition corresponds to /dev/nvme0n1p1
/ paration corresponds to /dev/nvme0n1p2
