Okay, well im trying to isntall windows 7 or windows XP... I have an external HDD and thats all... I've tried the USB flash methods (because its the same thing) and i keep getting MISSING NTLDR error... I tried stright upp copying a HDD with everything on it, and same prob... If i try installing XP (from my disc) onto the EXT HDD itll give me the Blue Screen Error. With windows 7 disc it says it cannot be isntalled onto a usb... can you guys help a bro out? Thanks.
