There are three ways to see Vista 64 installed.
1)Since you don't want any major changes on the first drive you
wouldn't be shrinking the 32bit primary at all to see a second or 3rd if
a second one already exists to see V64 added there.
2)Simply booting from the V64 dvd to see the installation go on the
second drive poses no problem while the V32 host drive is stll plugged
in except one. The boot files will be placed on that drive seeing the
BCD boot information changed along with seeing the 64bit edition made
the default OS until a boot order change there.
3)The optimum setup is first unplugging the Vista 32bit drive and
seeing a stand alone installation on the second drive isolating the
first drive from any change at all. Later you simply add the boot entry
for the 64bit edition into the V32 BCD file while still the 32bit
edition the default OS. The new entry is the only change there which can
also be removed later if needed.
The best free tool besides the BCD editor command line option for
seeing that done is called EasyBCD found at 'Download EasyBCD 1.7.2 -
