I just read through this post and tried to get my installation back using this answer to no avail. What happened to me is this:

I spent an hour or more reading through the CloneZilla docs. I thought I was ready to test it out so I burned the disc with the ISO image on it and ran it. The system I used was Ubuntu 10.04, 32-bit.

Everything seemed to go fine. I made a clone of my first partition and copied it to my second partition. I followed the instructions, removed the disc and rebooted my system.

At this point, I would expect to have two bootable Linux installations, identical to one another. However, upon booting, I got this error message:

error: no such device: 4cf1a6ef-xxxx-xxxx-xxxx-4e3a3ce92bcd

error: file not found

I booted from a Live Ubuntu disc and was able to see my to partitions: 4cf1(1) and 4cf1(2) (abbreviated, because the volumes have long numbers to identify them). The 50 GB partition, on which the original Ubuntu installation sits is the number and the second partition (175 GB) is the same number with an "_" at the end. I could browse the disc partitions and see the files, but I'm not sure what to do next.

I know there is a way to restore my grub loader and actually boot either of these installations, but my Linux know-how is limited. Can I edit the boot loader file to fix this problem?

The only clue I have is CloneZilla said something about making a new GRUB but I thought it was going to basically modify it so I could boot either installation. Not sure what happened. I am going to look through this post for the time being to see if I can learn anything to help my problem. But I thought that, since this happened as a result of using CloneZilla, it may be a unique question for this board.
