I know there are many dual-boot posts already, but I have tried most of the solutions without success. My situation differs slightly.

I have 2 hard disks. I am running Windows 7 and Ubuntu on sda1 (both are working well) and trying to install back-track to sdb (it is an SSD).

However, when I select backtrack from the GRUB menu, i get the error message: no such device: 3c19f052-1344-4e54-878a-4f7849e7882c hd1 cannot get C/H/S values you need to load the kernel first

I have re-installed several times, and during install, I always choose to install GRUB to /dev/sdb. (Chose sda once and it could not boot any of the other 2x OS as well)

Info from boot-repair is posted at --> everything seems in order. Does any1 have any hints?

This might be a BIOS problem. This article mentions similar problems using a SSD as a second bootable-disk.

I guess you stumbled on the same problem I set up a feature request on grub2 for: .

The problem is that your BIOS does not expect a second HDD - but a ODD (optical disk drive) on the connect port. Normally the problem results from modifying the hdd/odd configuration of a laptop.
