|Actually I re-read your post. |
I'd start with some other OS. Get a linux live install and see if it will load. Mint or Fedora or Ubuntu are pretty easy.
If it loads and you can install linux then it may be one of two things. One is you have a OEM disk and somehow it may need some driver that isn't on a Retail disk. Otherwise some oddity with the drive. Maybe have to remove jumper or go to cable select or set to different mode or something. Might even be power supply related to new drive. Might be some hardware got bumped or loose or damaged in install.
