Hello. I recently installed Fedora Core 5 on my system, on a secondary hard disk. I then added my /boot partition of Fedora Core to my BootMagic 8.0 bootup list. When I rebooted to get into Fedora, my BootMagic list came up, and Linux was "Unavailable". Does anyone know how to fix this?

BootMagic does no know anything about booting Linux. When you installed Fedora, you were asked about where to install GRUB. You have to point BootMagic to the partition the GRUB bootloader lives in.
