Dual Disk Dual Boot Issue Correction
There are some instances where a user installs a new disk drive in their Windows system so as to load Fedora. Fedora does not install grub in the MBR of the primary disk properly. For those instances this procedure will correct that issue.
Requirements
You will need one of the following disks to perform this solution:
- Fedora installation Disk 1
- Fedora Rescue CD
- Fedora DVD
Doing the work

Insert either the Fedora Installation CD 1, the Fedora Rescue CD, or the Fedora DVD then reboot the computer. At the Menu Options screen press the 'esc' key.
