Installation GUI completely screwed up

[elmasry.ayman]

I tried installing alongside windows 7 from a bootable Ubuntu 10.04 CD, the CD started loading the installation files but then I found the GUI completely screwed up and I couldn't see what was going on and the buttons where hidden, it was plain nasty... so what's up with that? I remember installing Ubuntu 9.x and it worked just fine about 7 months ago on the same computer...

Any ideas?

I have HP pavilion dv6736nr.

Bad burn?
Bad image?

hmmm... well I guess I should try to install from USB or burn it again first, I just wanted to know whether it's a unique incident or not.
