Windows 7 installation error "missing drivers"

[Dazzenh]

Hi, I was wondering if any one can help.

I have an acer aspire gaming computer which came with vista and I installed windows 7.

I have descided to format everything and install windows 7 again, but I have a problem when it comes to the installation.
After booting of the disk and then selecting the language. it comes up with starting set-up then an error message comes up saying "A required cd/dvd device driver is missing" if you have a floppy, usb etc insert with drivers.

It is a ligitment copy of windows 7 already on a disk, so i haven't downloaded it and burned it myself. Which i have read can be the problem, i have tryed to copy's of windows 7 and both have the same porblem.

Hope someone can help thnaks
