how do I format c drive when it has windows 8 on it

My laptop came with windows 7 preinstalled. I upgraded to win 8, now I need to format the hard drive and a box comes up saying I can't.

Why formatting the C drive, since Windows is installed on it?

gr82b :

What are you actually trying to do?
You can't 'format' a drive from within its own running OS instance. It won't do that.

if you upgraded win7 to win8 then you will have a windows.old folder created in case you wanted to go back to 7. deleting this folder will remove 7.
