I've Got the same problem here. I was using a nvidia geforce 8600 GT and Ubuntu Natty Live CD booted correctly. So I upgraded my video card to a geforce GT 240, tryed to install Ubuntu Natty (from USB) and got this strange screen. I am using Linux Mint 10 (based on Ubuntu 10.10). When I installed MInt 10 I was using the geforce 8600, but it works fine with my new geforce GT 240 with nVidia's drive. Maybe this problem is related with Ubuntu native drive?
