Solve : can't format C drive?

1.	Solve : can't format C drive?
Answer» When I go into disk management to FORMAT the main partition, I right click but the format OPTION is not ALLOWED. I ALSO looked in the help INDEX and it says you can't format the system partition. I am stumped.You cannot format the system partition while the system is running. (Can you guess why not?) Then how do you do it? Obviously I have no idea what I am doing!Boot to the OS CD and you'll be given the option to format before reinstalling.I did this and was not given that option. I'll try it again. Thanks!http://support.microsoft.com/kb/304868
