well you'll just have to unformat it won't you :D
seriously though..... did you install the boot loader to the MBR? I'm assuming you did - I'm also assuming you're using XP (as you still haven't said which windows OS your using!) since you refer to diskpart rather than fdisk.... in which case you'll need to use the recovery console and type fixmbr
These might help you
