Why a new disk, cloned with clonezilla, cannot boot ( end up in grub prompt) ?
by gsoucy from LinuxQuestions.org on (#5G2CM)
Hello,
I did a complete clone of a disk (disk-to-disk with all partitions) using Clonezilla.
The clone was successful but when I try to boot, it fails and I end up with the GRUB prompt.
The disk contains a Centos 7 installation and I understand that grub refers to the boot partition via its UUID (in grub.cfg) and the same UUID is used in /etc/fstab for the /boot partition. However, if I clone the disk, dont I also clone the UUIDs and then grub and fstab should find the right partition.
What is wrong in this hypothesis ? Do the actual partition id change during the clone process ? What is different between the original disk and the cloned disk that make the original disk boot normally and the cloned one fail booting ?
Thank you !
Gilbert
