Hi all,

I am in the classic situation of overwriting my grub boatloader after
reinstall of Win 2k Pro. Using RH Linux 9 and trying to restore my dual boot
grub loader.  When I try reinstallation from CD adn restore loader it won't
work.
The windows and RH Linux exist on the same hard drive.

I need to restore it on the MBR I understand.  Whats the best way to go
about this?

Thanks

Michael
