Here is what I mean by this. At that time, I had the 100GB hard drive (the one with GRUB and Fedora on it) set in the BIOS to boot first. Every laptop has a way to change the boot device selection during POST (mine is by hitting F12). Then, I get a list of what should boot first. If I selected the 80GB drive to boot first, it would go straight to Windows without a GRUB menu selection. The only changes I made to the boot order was in the BIOS, and my assumption was that since I never saw the GRUB menu that it wasn't being used. This is what I meant by "switching the primary boot disk". Then a couple months ago, I wanted to use Fedora, so I decided to try repairing/restoring GRUB on the 100GB hard drive. After I did that, I got the GRUB menu selection again and I could boot into Fedora, but then I couldn't boot into Windows (see post #1).

GRUB was installed on the hard drive with Fedora on it, so I bypassed this by switching the primary boot disk to be the Windows drive. At this point I could boot straight into Windows, but I couldn't boot into Fedora.
I suppose that this is a little misleading. What I meant to say was I haven't been able to do this since I repaired GRUB a couple months ago.

can you still boot windows without grub ?
No, I've never been able to do this.
No. The only boot order I have changed is in BIOS. I have left the boot order of grub alone.
do you mean you changed the boot order in grub ?
I assume that it did when I could boot into Windows, but at this point, I don't know. It's possible it could've been overwritten when I repaired GRUB. How would I check this?
has windows got its bootloader in the mbr of its own drive ?
