As far as I can see, the original poster made no mention of any Linux or Unix installation; he posted in the Windows Vista section; he mentions he is trying to use a "Spanish version of Windows". Also, I suspect that "juke box" is a typo or mistake and "junk box" is what is meant.
Anyhow: Retireded, the answer to your question is "Each installation of Windows is tailored to the hardware found at install time. In most cases, therefore, you cannot move a hard drive with Windows on it to another computer and expect it to work. In your case you definitely cannot, as you have already found". Any ideas? Using a legal, properly licensed Windows install disk, format the hard disk and make a fresh install of Windows.
