I'd like to be able to multi-boot Vista Ultimate x64 and Windows XP SP2 (32-bit) while they're each installed on a separate hard drive. Is this possible? I'd like to have it so a boot menu comes up automatically that lets me choose which OS to boot. Also, I need to be able to access files from one OS on the other OS.

How do I got about doing this? Thanks for any help.

First thing we need to know, is what will be the main OS you intend to use, I mean, what will you put on C:\ ? What will you install first, or do you already have one installed?

Then I suggest to keep at hand an utility that allows you to easily enable multiboot and "EasyBCD" is the best application to achieve this.

But before you move a single finger, please have a printout of these two amazing "how-to's" , they worked great for me:
