I have two hard drives /dev/hda and /dev/hdb
/hda has windows on it
I booted off my Fedora Core 4 DVD and did a install as to install it on /dev/hdb
By default I chose to install the mbr on /dev/hda
It loaded fine, but upon restarting it just goes to win.
I changed my bios to boot off my second hard drive.
Still it didnt do anything exept display "Error Loading Operating System"

This procedure worked great with Fedora Core 3 and CentOS in the past.

Any ideas would be greatly appreciated

"By default I chose to install the mbr on /dev/hda

Use a rescue CD to boot into your new Fedora Core 4 system. Then edit your bootloader configuration file to straighten out the problem. If you are using lilo then the configuration file is /etc/lilo.conf. If you are using grub then the configuration file is /boot/grub/grub.conf.

After you have the bootloader configuration file straightened out then reinstall the bootloader to the mbr. With lilo the command is:
lilo
With grub the command is:
grub-install /dev/hda

Here is a grub manual:
