Had amd64 Ubuntu installed (dual core AMD C-50, assumed it was 64-bit), system locks up randomly. Created a i386 boot usb stick using the disk creator on a Toshiba Satellite running 11.04, try to go back to Acer to boot off of it. Get to boot load screen, select language, select install ubuntu, goes to boot into the system instead of install process.

I'm about to grab my Gentoo livecd and toast the harddrive and start from scratch. Would rather not but will if I have to (still going to put Ubuntu on the lap top, it's for a guy who used to use Windows). I've installed (successfully) Ubuntu on 6 computers, two of them laptops. This is the only computer really giving me fits. Any ideas? Anyone else having the same issues?
