You can edit grub.cfg as you want.
Usually, I mount /boot as read-only.

In reply to steve. @Steve, To change the UUID (Universally Unique Identifier) of a Linux partition, you can use the tune2fs command. 1. First check the current UUID of the partition using the blkid command.

sudo blkid /dev/sdXY

2. To change or set the new UUID for the partition use the tune2fs command.

sudo tune2fs /dev/sdXY -U new_uuid

3. Confirm that the UUID has been changed by running the blkid command again.

sudo blkid /dev/sdXY

4. If the partition is mounted at boot time using the /etc/fstab file, you may need to update the entry with the new UUID.

sudo nano /etc/fstab

Replace the old UUID with the new UUID in the corresponding line and reboot the system.

This article describes changing a FILESYSTEM UUID specific to an EXTn filesystem, and NOT a partition UUID. Completely useless for other filesystems, or for a partition UUID.

In reply to W.C..

Exactly, I was searching for ways to change a PARTUUID, I already know how to change filesystem UUIDs.

So this page is totally misleading.

This isn’t about changing the partition UUID at all (PARTUUID in blkid output), but the *filesystem* UUID within the partition.
