try booting the FC-6 Installation Disc 1 or the rescue CD and typing at
boot prompt...

linux rescue

after it boots, it provides a message and offers to 'mount' any FC-6
installations it finds (good idea)

You can confirm the installation by typing at command line...

fdisk -l /dev/hdb

it should list at least 2 partitions on hdb...

approximately 100 mb /boot partition
balance of partition in one big LVM partition

If you can locate those, you could try...

chroot /mnt/sysimage
grub-install -v /dev/hda

which should install the grub boot loader onto the boot blocks of the
Windows drive.

then 'exit' and 'exit' should cause it to reboot and bring up grub
bootloader
