Ok, that's very strange. I've used the same Ubuntu installation to boot on machines which not only had different motherboards, but different architectures (i.e., AMD-based on one and Intel-based on the other). I've got an Ubuntu installation on a thumbdrive that I've literally used to boot from a dozen or so different machines, too. The only reason you should have a problem would be if you had a 64-bit install and are now on a 32-bit machine. But that is EXTREMELY unlikely. What exactly is happening? How far is the boot process able to go? Do you get to grub at least? My instinct is to hold Shift while you boot, edit the grub boot line and remove the "quiet splash" part, that'll give you a more verbose boot process that'll be much much MUCH easier to debug. -Yaron --
