I can not reformat the Dell Inspirion Laptop that runs windows 7 to run. Attempted to use the Operating System Recovery Disk that Staples created but can not get past the first one. Used Bios to boot from disk and can get to starting windows after installing the first disk, then thats it it goes back to black! Staples isn't helping unless they charge us. The Laptop has been down know for six months or so. I know that if I had a proper windows 7 disk and not a recovery disk I could get it running.
