Looks like for some reason the graphics drivers that come with the Live CD are having problems with your graphic card. What graphic card do you have?

Also, while you can use the Live CD (normally at least) to try out the system, you could also run it via WUBI. You should be able to start WUBI when you first boot into Windows and then insert the Ubuntu CD. Maybe that gives you better success? I have never tried WUBI myself, so I can't say for sure, but if it does indeed generate a second entry in your boot loader, you should be able to give certain command line options to the kernel before it starts, so that it runs in safe-graphics mode.

Can someone who has done this kind of stuff please comment? I personally never had difficulties like this before, so I don't even know what the right options would be.

could also be your screen not being detected correctly and thus wrong refresh rates (and Horizontal Sync) used. graphics support is typically good and NVidia geforce is supported.

do you see text on your screen if you press ctrl-alt-f1 ? (press ctrl-alt-delete to reboot from here)
what type of monitor and connection? (HDMI, DVI, RGB, etc?)

i havent tried ctrl alt f1 but i did try booting it in safe graphics mode and it said i was missing an nvidia driver. but i cant install it because im only booting from the disk so no changes will save anywhere. so i think theres a driver missing.

i have a new issue though. i made a bootable usb drive with the inbuilt feature but my computer wont boot with it. i changed the boot order in the BIOS to have usb first and it tells me the device is not bootable and defaults to vista. any ideas here?

If it is USB bootable, have you tried F12 on startup before your OS loads, which should present you with a list of bootable options, with one saying 'USB drive' or something to that effect.

Seems a little odd, since that graphics card isn't uncommon.

Does it display any errors while booting?

The disc should have a boot option to scan the disc for errors, you could try that.
