Is it possible to get my windows 8 serial number by using command prompt? Before you try to tell me to go download this or that.. instead.. No... just no. I cannot get anything too boot including windows the only thing my computer is recognizing is my recovery disks which don't work but I have a solution if I can get my windows 8 serial number. Before you say, hey just look on your product, or call support they'll be able to pull it up.. NO... Already tried that.. No tag on the case, support doesn't do that since 'windows serials are imprinted in the system so we cannot retrieve it'. Or give me a command to use to wipe this hard drive clean using the command prompt that is only accessible inside the the windows boot drive that only allows me to use Shift + F10 cause there is an Error screen after bios. FDISK does not work. Erase only erases non system files, Format, only can format other hard drives that my windows installation is not on. No i cannot access another DVD drive and no i cannot get access to another hard drive. If you get through this and think you can help me. I really appreciate you taking the time to help.
