I have a Alienware M17 r4 and I'm a member of alienwarearena.com which is an Alienware forum. The person who you got the laptop from should also have the discs as the Alienware windows disc is different to a normal windows 7 or dell OEM disc as a few members of the Alienware forum who have lost the disc and tried to install with a non alienware disc and ended up having the same problem your having now. If he hasn't got the Alienware discs he may of created an image on a pen drive or on disc made with Alienrespawn its Alienware's own backup media and if he or she hasn't any of mentioned above and will not contact Alienware to get the disc then you want to head over to the Alienware forum and you should be able to get an iso of the Alienware disc.Hope you get things sorted soon as you will have an awesome gaming machine
Thank you for your reply. I already have the Alienware disc that came with the machine. It is the one I used during my initial attempt to factory image restore.
