Cannot do a clean install of 10.04

I currently run Win XP Pro x86 and I recently installed Ubuntu 10.04 as a side-by-side operating system and everything works great. I decided to burn the iso image to a dvd and was planning to do a clean install with 2 partitions, one for Ubuntu and one for XP. I am able to get the dvd to boot to the loading screen, and have even tried changing the boot loader for the laptop because I thought it was a display issue at first, but still no luck. I can see the first loading screen with the Ubuntu logo, and the dots below it that change colors as it loads, and I've hit F1 to change that screen to watch everything as it boots to see if I can catch any errors, but I am not able to find any errors. It looks like it gets almost done booting up to begin installation, when it basically crashes. The screen goes blank and everything stops responding, the dvd is no longer spinning/being read, keys do not do anything, Ive tried an external display even but the display goes blank on the external display as well, at the same place. I cannot figure out why it won't work on this laptop from boot, but works just fine when I install it from Windows as a side-by-side.

Basically I intend to do a side-by-side installation but I want to install Ubuntu, with a clean partition first, then XP in its own partition.

The laptop I am having troubles with is an older model Toshiba. I have tried a clean install on my much newer Dell laptop and it installed very fast with no problems, but the video card in the Dell has about had it, or I would just use it.
