Well I just had to replace all my hdds since they all got fried, so now I have to install windows again. All I have to install it with is my 80gb external drive. I got the drive formatted and put the 64 -bit OS on it, but I can't make it bootable. I keep trying to run bootsect, but since my laptop is running 32-bit, so it isn't letting me run it. Is there anyway I can make my external drive bootable or do I need to go buy a usb drive and use microsofts usb tool?
