Windows 7: Windows 7 install stuck at 0% on "expanding files" but works off USB

I torrented a windows 7 install disc iso. I burned it to a disc but when i tried to install windows 7 it gets to "expanding files" and freezes at 0% . After that i tried using the exact same iso but from a thumb drive, and it worked. I tried the disc on multiple computers and it always sticks at 0% on expanding files. I have also reburned the iso multiple times and it still doesn't work. If i use a jump drive it always works. I know someone is gonna say that its the iso because i got it from a torrent, but the same iso works from a usb drive so it cant be that. I know someone is gonna say it is the optical drive, but i have tried it on 3 different computers with optical drives that i know work but it still sticks at 0% so its not that. Its also is not that i haven't waited long enough because i have left it for multiple hours and it still didn't move from 0%. I suspect that its an little feature in the burning program that i overlooked during the burn process. Has anyone encountered this or know how to fix it?

I assume it has to do with the burn speed. If burned at anything higher than 1x, there is a chance of the disc being corrupted.

Is this Clean Reinstall - Factory OEM Windows 7

If not how are you activating Windows 7?
