[RESOLVED] Ubuntu linux will not boot from multi boot system after clone

Thread needs solution

I have a multi boot system Windows XP, Windows 7, & Ubuntu 12.10 linux. I use Acronis OS Selector and it works fine. I have cloned the drive with these systems, using True Image 2013. However, when I reboot using the cloned drive all of these three systems show up in the OS Selector menu, but only Windows XP and Windows 7 will boot. Ubuntu will not and the computer restarts.

Any suggestions? Thanks, Fran

Fran:

Ubuntu uses Grub2 for a loader, and it probably works like the original GRUB; that is, the Linux loader references a specific sector location on the disk, and a specific disk ID. If you have created a clone, the references are probably different on the new disk. You need to update or reinstall GRUB2 to fix this.

You can find information on how to do this on the Ubuntu forums. I used to know how GRUB worked but have not kept up with what's different with GRUB2, so I can't give you the specific command needed. You might want to try this utility: http://sourceforge.net/p/boot-repair/home/Home/

Don't let in run in automatic mode because it will probably want to install GRUB2 to the MBR of your disk. Since you are using OS Selector as a boot manager, you'll want to reinstall GRUB2 to the Linux partition instead.

Good to know!
