root=UUID lines are normally interpreted by the initramfs to find the right device to mount. If you don't use one, the kernel pretty much only supports root=/dev/<name> or root=PARTUUID identifiers (check kernel source file init/do_mounts.c:182,207 for details). You can find your PARTUUID using `blkid` or `lsblk -o +PARTUUID`.
