I suddenly got the same problem in /efi/loader/entries all conf files reverted to previous uuid (first post ). To change uuid I just edited all conf files with the correct uuid for root.

I don’t know if manually changing was correct or if I should use some sort command.

Bootctl status

UUID in status is wrong.

I have no idea what is reverting UUID back to the wrong one after updating system.

I could just reinstall but if possible I would like to try to fix this and learn.

Edit: Problem was that in /etc/kernel/cmdline had wrong UUID. Changed it to correct one and dracut-rebuild uses correct UUID.

    I think the key would be figuring out where this extra UUID is coming from. Maybe next time you try this, make a note of all the UUIDs on your system (including the bootable USB) and see which one ends up in the bootloader config.

    Knowing what’s happening can help guide your Googling to find out why it’s happening and how to fix it.

      I used gparted, blkid, checked fstab and by-uuid dir and no partition or drive had that UUID.

        Weird… the only thing I can think of is that maybe the UUID changes on every boot with live USBs, since the root filesystem is ephemeral …

          I think I found what changes root UUID. When I used dracut-rebuild all entrie UUIDs changed to the wrong one. Now I have to find how to stop that.
