Windows 7: Unexpected error on multi-boot system

I'm attempting to do an upgrade/update install of Windows 7 Professional over Vista Business. Everything checks out with the update advisor, the anti-virus and anti-spyware programs have been turned off (I have, however, left the Windows home-grown firewall on), but shortly after the temporary files have been copied and the setup begins, I received a dialog box saying that an unexpected error has occurred and that I should retry the installation.

My system is multi-boot with the first partition for Windows XP Professional, the second with Vista Business, and the third and fourth with OpenSuse Linux. I'm trying to upgrade/update the Vista partition. SP1 has been installed for Vista, and all of the updates contained in SP2 have also been installed.



Sorry to waste your time if there is an obvious solution to this , but I haven't yet seen it in this forum or anywhere else. Thanks in advance for any help!

Hello Clip5, welcome to SevenForums.

I honestly to not suggest an upgrade, it tends to cause more problems. As to the others you have installed. Perhaps it has something to do with OpenSUSE. Do you use Grub1 or Grub2 for a boot loader? (Or something else)
