Has to be a boot install.

You can't format that because it is your main drive and it contains all of the windows files. If you do that then your computer WILL stop working.

Hope that helps

You will just have to do re-installation.

restart your system when bios is loading press esc or f10 (depending on manufacture) to enter bios then go to boot tab select cd drive as booting drive then save & exit.

when your system start again it will load window then it will show you install option select cutom fromat d: (it will delete your data) format C: then install

tell me if it work
