Did you change both kernel param and fstab ? You can use /dev/xxx in fstab, no need to know the uuid. You can also add the kernel param biosdevname=0 to get the old name. In this case your nvme should be the first so named /dev/sda. If you don't remember partitioning you can install cygwin and use fdisk on it. cygwin also provides blkid to get label and uuid.
