hi i want to boot windows7 from my harddisk which i am using . i mean to say that not from external hard disk drive. i will try to explain again, actually i have a pc on which i am working at this time (internal or primary harddisk drive of it ). i want to reboot my system and when its bootsup then it should be stating setup of win7 from one of my harddisk drive. for example from d: drive (D:/win7) and also want to fromat my c drive.
