If you have your hard drive you want to boot off as master, and the one you don't want to boot off as slave, I believe you should be alright. If that doesn't work though, you might have some settings in the bios that lets you choose which hard drive to boot off first. If your not running windows off the hard drive you want to reformat, you should be able to reformat it then.
Are you ok on the hardware installation process? Your newer computer might use Sata and the older one might use ATA (IDE) hard drives. Your newer computers motherboard probably still has IDE ports on it though, so you should be alright, even if it uses Sata, and the old one uses ATA.
