I've just installed windows on a computer with 2 hard drives and to my amazement it has designated the drive that windows isn't installed on as C! So I have a drive with 244kb of free space set as the C drive and the drive with windows on it set to J, thanks windows. 
Is there anyway to change the drive with windows installed on to the C drive?
