Ok last time I reformatted my hard drive I had to do all this stuff. First I had to set it so it booted from the CD Rom Drive, then I had to go into DOS and do some partition stuff and all that. It took quite a while but it worked great. My friend told be about going into a DOS prompt (which I am very comfortable with because I program in Python) and typing 'format c:' I was never really aware of this. I was just wanting to ask is it safe? Does it do the same job as all the other steps I had to take? Will I be able to reinstalled windows? Thanks.
