I have just bought a larger Hard Drive,the one installed was quite small.I want to use this new drive as the master,and the other will just be used for Data.I have formatted this new drive and can now transfer info from my original disc to the new one.Do I have to reinstall Windows on this new disc before I can use it as the Master and the other as the Slave.?
Quick answer YES, you need to reinstall windows as when you set up your new hard drive as master it should become the "C" drive and the system will look here for the OS but it will be on your old drive "D"
Installing Windows again will give you a clean install, it may be a little more work, but programs should run faster and you'll clear out any junk you don't need/want. Then all you have to do is copy everything you want, documents etc. from your old drive (now the D) to the freshly installed Windows version on C. Then format your old drive to free that up.
