Thanks again for the information.

Thanks for the info... I've included some screen shots of the boot menu, and the BIOS. I'd like to do the Windows upgrade by disconnecting the OS X drive. Will the Psystar boot menu then work by clicking on the Vista choice to boot 7? (Is this label just a link to BIOS Hard Disk Boot Priority # 2. SCSI-1?)

Hi, I need to upgrade my Windows OS from Vista(x64) to Windows 7(x64) on a dual-boot computer. I didn't build the computer myself, and don't want to screw up the Macintosh side when I do the upgrade. This is not Apple hardware. When I boot up I am pressented with a non-windows boot menu, which lists OS X Leopard and Windows Vista. I'm trying to understand if this boot menu is launching from the OS X hard drive. If I disconnect the power and SATA cables from the OS X hard drive, I don't see any boot menu, and the computer boots directly into Windows. Would a Windows upgrade install be as easy as unplugging the OS X drive and running the installer, or am I missing something? Thanks in advance, Drew Here is an image of my disc management in Vista:
