Re: its either me or the hard drive
As demonstrated, you can't boot into an installation of Windows from a different machine, on another machine which has different hardware. Sometimes it works, but it almost always fails because the Windows partition (originally installed on a different machine) does not have the correct drivers installed for the new hardware on the host machine.
As for gaining access to your files on your old hard drive, once connected to your new computer, you need to take ownership if the folders and files in order to be able to read and modify them. Search google for help on how to take ownership of files in Vista / XP (depending on what OS you're currently using).
