Not possible. The problem is somewhere else. A bootable PW disc cannot make windows slower etc.
After startup, you were getting into the newly attached drive (old one) ... for it you need to change the boot priority. Enter into the BIOS, set the previously attached (new) drive at first boot device, or second, after the Optical Disc Drive.
Make this change, and reboot. Is the situation the same ?
