Before Windows 7 was officially released, I tried installing Win 7 RC1 in an empty snapshot on my Vista system using the instructions posted in another thread by pandlouk. It "sort of" worked--I could boot to the Windows 7 snapshot or the primary Vista snapshot, but not to any of the other snapshots I had. When Windows 7 was officially released, I decided to install it in a new partition. I first uninstalled FD-ISR from Vista and then installed Windows 7 in a new partition. I can now dual-boot to either Vista or Win 7. I'll wait for the Win 7 compatible version of FD-ISR before installing it. But here's my question: if I install FD-ISR (Win 7 compatible version) on Win 7, will I still be able to dual-boot? That is, will the Windows boot menu come up first, and then if I select "Windows 7" will the next screen be the FD-ISR menu? Or will the installation of FD-ISR wreck the Windows boot manager? I know this is speculation at this point, but I'm wondering if anyone has FD-ISR installed on a dual-boot system, like a Vista and XP dual-boot configuration, and has FD-ISR working properly. Thanks for any ideas.
