How do I reset my WIN8 computer to factory settings with CMD?

[Chadders101]

Hello everyone!

My computer is absolutley screwed and I would like to reset it. Completly and utterly.

I only have access to the start-up repair, and therefore command prompt. I have tried all possible deviations of all possible options in the menus provided and they have all circled back to the start-up repair. Apparently my WIN8 disc is invalid or whatever, either way I can't use it and I don't know why. The only options I can see are to buy a new hard drive and install WIN on that which would be rather expensive, or to try and find a command chain in CMD which resets my computer to factory settings.

I have a rather powerful computer. Some parts are two years old, some are two weeks old. This problem originated when I was using Skype and a game called "firefall" and my computer blue-screened and I got the error "critical_process_died". Now, when I try to start my computer, I get the error " 0XC000021A" which I believe means a startup error.

So, is there a command prompt which resets my computer completely? Or will I have to buy some new hardware?

This would seem to be the problem.
Why is this?

Where did your install media come from?

I bought the windows 8 disc two years ago to install onto my computer with no existing OS. It worked fine with no noticible problems when I first used it so I just thought everything was fine. I bought the disc off of Amazon.

I don't know why it is considered invalid media now and I don't know how to fix it.

I would love to supply more information to fix this problem. Also, that's for the speeds response.

So...booting from your Win 8 install media...what happens, exactly?

Nothing happens. My computer pretends that the disc does not exist and tries to boot up normally, which it can't do. Like I said, when I try to force it to recognise the disc, I am told that it is invalid media.
