Debian and Fedora on one drive?

["Karoo" <kleinjie@kopjie.com>]

  Hi.
I recently bought a 40 GB Maxtor and loaded Fedora onto the first 20 GB,
leaving 20 GB free.
Fedora was working O.K. so I loaded Debian Sarge onto the free 20 GB. During
the Debian install Grub wanted to know where to be put (out of 3 options)
and I chose the MBR. I was hoping it wouldn't happen but of course it did,
it overwrote the Fedora bootloader.
I don't want to know how to fix this, just how does one make the install
work for two distros.

Many thanks.
