jas340 :
Put old drive back in. attach larger drive to another SATA port. Clone old drive onto new drive. Lt will be an exact copy. I use Acronis true image. There are free cloning programs on internet. If this is a laptop then it will be more complicated.
I unplugged all hdds except my new one, and got windows installed.
plugged back in my other two sata hdds and the pc is having trouble recognising them.
It seems to be stuck on the driver software installation thing now. Searching preconfigured driver folders.
Been like this for at least 30 minutes.
Any ideas?
