First of all gpu drivers has nothing to do with your problem.
Please post in complete details of your motherboard and both hdd so that it could be identified whether drives are sata/pata.
my new motherboard is asus p8p67-pro-b3. my old hdd is a seagate 500gb while my new one is a seagate 1TB. i want to use my old drive just for storage. and i want to remove all the drivers and the windows 7 os thats inside the old one. im currently using windows 7 ultimate edition
@ OP - on your new PC the 1TB HDD must be the boot drive .. just connect the old HDD ( is this is a sata drive ? ) with your new mobo.
The mobo bios and OS will auto detect the new HDD and you will be able to use the HDD just fine
yes it is a sata drive. my new !TB hdd is the boot drive. but the old one has windows 7 as well. are u sure that it will not cause any problems on startup? also, even if i am able to boot normally from the new hdd, how do i remove the old os and user files from the old hdd? want to format it cause i want to use the full 500gb
