My windows xp crashed and i cant get it to reformat. When i place my windows xp set up cd and when it gets up to the "setup is loading windows", i get this error: "a problem has been detected and windows has been shut down to prevent damage, check to be sure you have adequate disk space. if a driver is identified in the stop message, disable the driver or check with the manufacturer for driver updates try changing video adapters. check with ur hardware vendor for any bios updates. disable bios memory options such as caching or shadowing if u need to use safe mode to remove or disable components, restart computer press f8 to select to advanced start up options and then safe mode.

It is a little more than 2 years old. It crashed when my keyboard was stuck on Maplestory. I wanted to restart my computer. I restarted it and my whole computer froze so i pressed the power button to turn it off because it was my only way. When it started to load, i got this message: "Windows cannot load because the following file is missing or corrupt: /windows/system32/config/system." When i try to reformat it, i got the error i mentioned above. How do i fix this? Its pissing me off. How do i prevent this and bypass it? is it the disk? is it something else? what do i have to do? This is the only thing that is blocking me from reformatting and fixing my problem D; . Oh and Ubuntu is installed. Someone installed it for me and i don't think it was partitioned. Does that mean anything? i don't have files on ubuntu i need to keep or have anything actually. I Just want windows back D: any help is appreciated! Thank you very much for your time. I am not a very techy person so you will have to explain. this is the first time my computer crashed so i dont really have much experience.
