I've had a dual boot Vista/FC6 and now F7 laptop running for about 6 months with no problems. I used EasyBCD to extend the Vista boot loader to chainload GRUB on another partition. It's worked without incident for a long time.
Now, Vista still works normally (well, as it does), but after selecting my F7 option (from the Vista boot loader), the screen goes blank then "GRUB read error" appears in the upper left corner ... and that's it. A 3-finger reboot is required, no Fedora.
I've read a number of posts and it seems that the error is caused by STAGE1 not being able to properly load STAGE2. The Rescue CD has no problem mounting the partition and everything looks like it's there (including everything in /boot and /boot/grub)... just can't seem to boot it. 8-(
My F7 partition is /dev/sda5 or (hd0,4) in GRUB-speak. From grub I've tried:
It seemed to complete normally, but the same "GRUB read error" message appears on boot.

Is there a reason/way to try grub-install if I don't want to mess with the drives MBR? Will it do something that my grub commands above have not?
Since I get the "GRUB read error" message, does that mean the Vista boot loader has properly chained and GRUB began running? I.e., Vista hasn't hosed the F7 GRUB, right?
What should I try next? And, yes the Vista must stay (anything that doesn't kill you only makes you stronger). 8-)
Thanks for any consideration.
