Let me start off by saying, I've been trying to run Ubuntu on my custom PC for about 2 years. From 10.04 to 12.04, this problem persists.
When I try to boot Ubuntu from either a USB stick or a CD, I see the normal Ubuntu splash screen. It looks like it's working, orange dots are moving, but then the screen glitches and freezes.
I'm assuming this happens because there are no drivers for my graphics card (Nvidia GeForce 8800, I think). My motherboard has no onboard graphics, nor does it have a VGA out.
So, how can I get this working on my system? Can I somehow put the drivers along side the .img on the USB stick?
I can boot from my Ubuntu USB stick on my MacBook. In case that helps anyone...
