Double Booting

Hi, I'm running Windows 7 Home Premium 64-bit version and I need to install a 32-bit version of another Operating System (XP, Vista, 7, either one is fine).

This morning I created a partition to install Windows XP Professional 32-bit version, little did I know that it would result in Windows 7 crashing...

Apparently I cannot install Windows XP on top of Windows Vista/7, but I could do it if I had Windows XP installed first and then proceeded to install Windows 7.

I lost about 8 hours trying to fix my computer after this happened... After having it fixed I found this:

http://support.microsoft.com/kb/919529

Now my question is...

Would it be possible to install Windows Vista on a different partition, even though I'm running Windows 7 on the main one?

I want to be able to choose either Windows 7 or Windows Vista at start-up so, if you don't have the answer, please take your time to read what I found on microsoft's website (http://support.microsoft.com/kb/919529).

Even though I speak fluent English, I can't understand if:

A) I can't install older versions such as Windows XP on top of Windows Vista/7...

or

B) I can't install older versions on top of a newer version, Windows Vista on top of Windows 7 for example.

Sorry if I'm too confusing, and thanks for the help in advance!
