What motherboard do you have? Is it an "ASRock"?
I have had the same error on several PCs with "ASRock" main boards. I tried different DVDs (DVD+ and DVD-) and different DVD player. Always the same "error 5". Seems to me that THIS motherboards can not boot from THIS Windows 7 boot DVD. Other boot DVDs works fine with this "ASRock" mainboard; e.g. Vista boot DVD.

I have connected my hard disk to an other PC and start the install. After the first reboot (because: before the hardware detection starts) I moved hard disk back to the PC with "ASRock" main board and finish the installation.
