I used clone-ubuntu.sh script to clone my ubuntu system from HDD to SSD. The script also changes UUID of SSD. I have both HDD and SSD connected to my laptop. Now there is a grub entry for SSD but when I try to select (i)ubuntu from the SSD, some lines appears on screen [ok] did this, did thatxxxx. There wasn't any error on that screen. But after all processes are done, my system boots up from old HDD. When I select (ii)ubuntu from HDD that screen with [ok]message never appears.

I have checked my UUID by ls -lha /dev/disk/by-uuid command. sda8 is HDD's ubuntu and sdb3 is SSD's ubuntu

Output

  • Did you reinstall grub and change UUIDs in fstab, so new UUIDs used not old one's on HDD. I typically find it easier to just do a new install & copy /home, data & list of installed apts from backup. Your backup should allow quick reinstall, anyway. When hard drive fails that is the way you have to restore to a new drive. Compare lsblk -o name,mountpoint,label,size,fstype,uuid,partuuid | egrep -v "^loop" and cat /etc/fstab – oldfred Oct 27 '20 at 15:17
  • The cloned file /etc/fstab is modified with the appropriate UUID for the partition it is on.
  • The cloned file /boot/grub/grub.cfg is modified with the appropriate UUID for successful clone booting.
  • update-grub is run to update Grub with new menu options pointing to the cloned partition. These points are from the scripts I ran. And as per ls -lha /dev/disk/by-uuid output. UUIDs are different

  • May or may not show something. Lets see details, use ppa version with your live installer (2nd option) or any working install, not Boot-Repair ISO: Please copy & paste the pastebin link to the Boot-info summary report ( do not post report), do not run the auto fix till reviewed. https://help.ubuntu.com/community/Boot-Repair & https://sourceforge.net/p/boot-repair/home/Home/ – oldfred Oct 27 '20 at 15:54
