Ok, guys. I have a problem I have been talking to others about on this forum but getting nowhere. I want to dual boot with Vista already installed. I can't get 7 to see my F drive, which is my second internal drive and where I want 7. Could it be because the first drive , the one containing Vista, is a SATA drive, and the F drive is an IDE drive? I was told to format F and not to make it active. No good. I was told to make C inactive, can't figure out how to do that.
Jim, I had a very similar experience when installing the first Vista beta, and I think your problem lies with your F: drive being an IDE while you have a current OS on a primary SATA drive... as in the IDE does not have the appropriate drivers loaded, and thus Win 7 can not see it. However, you can NOT disable your primary OS drive within the OS itself. What you would need to do is open your rig and unplug the Sata drives. Win 7 should then see the IDE drive and you will be able to install it.
This, however, would make the IDE your primary OS drive at boot when you plug the Satas back in, and (given Win 7 is still in beta) you would want to change HDD boot priorities in the Bios to make the Vista drive the primary... there's also a setting in msconfig> boot (either OS) to set the default OS. You could also run the Vista disc and do a repair to make it first boot, though it's not overly important as setup provides the option to choose OS via the k/b up down keys.
I'm no expert, but this was my experience and your issue is much the same, so the same 'should' apply. However, somebody more knowledeable than I may have a better/simpler idea that works, so you might want to wait and see for a while.
