Dual OS Vista 32 and Windows 7, 64?

[gumi]

Ok so I have 320g Hard drive that came with my PC. Right now its completely full.
I just puchased a 500g HDD and was thinking about putting windows 7 64 on the 2nd hdd but wasnt sure if that would mess anything up being on a separate hdd or if having a 32 and 64 bit OS on 1 pc would mess anything up.
