You were facing no problems before because the two linux distributions 
you had installed were using GRUB legacy. Now you have add a new player 
(GRUB2) to the booting game and that's why you may need to tweak the menu 
so you can boot Mandrake.

Neither do I but I (and "you") do know how to search, right? ;-)

Okay, when you are in GRUB2 menu, press the "c" key to reach the command 
line mode. From there you can start to speak with GRUB2 and run commands, 
for example (this is just for demo purposes with a minimal set of 
options, I don't know if it will work for you "as is"):

set root=(hd0,3)
linux (hd0,3)/boot/vmlinuz-2.4.22-10mdk 
initrd (hd0,3)/boot/initrd-2.4.22-10mdk.img
boot

Remember to press the "Enter" key after every command and (very 
important!) watch for the ouput. The goal here is that GRUB2 can find the 
Mandrake root partition and boot the kernel image from it.

Oh, come on, this is linux, marine. You've been trained to be prepared to 
survive these kind of situations (and even worst) :-P
