but i'm uploading vista or i was going to, and i know the disc works as i saw it upload the operating system onto a computer at work, but for some reason my computer wont read it. It is on a DVD and i can still play DVDs. but NOTHING happens when i put this disc in...it makes a slight humming noise for a second and then just gets bored and there is nothing about it in my computer.

A bit heavy for a sunday, but id like to do this tonight so i don't have to take my laptop into work tomorrow!
