Hi i've just built a htpc and have installed a Seagate 3tb Barracuda drive but i've got a problem i can't seem to sort. I started to install windows 7 installation and go to the screen where you pick what harddrive to install windows on. I wanted to partition the drive into 500gb for windows and the rest for files ie movies,mp3 and so on but i over shot the 500gb to 750gb. So i clicked delete partition to change to the 500gb i wanted but the the 750gb partion will not delete. I even tried to install windows on the 750gb instead of downsizing to 500gb but i get error 0x80042468. How can i get the drive back default size.
