Were you also looking for advice on how to go about doing so? – Jason D Nov 29 '09 at 23:49

Yes, if your hardware supports a 64-bit operating system, you should be able to dual-boot to 64 bit Windows 7.

One OS is not influenced by the other. They can both be installed on the same PC without any problems. – alex Sep 22 '09 at 14:42
I'm currently running the reverse: XP x64 and Server 2008 x86. There a no problems with this configuration at all, except that I don't use XP anymore. – Stevoni Sep 22 '09 at 15:14
