triple boot question

[OttawaNoob]

HD0 - Windows Xp
HD1 - Ubuntu
HD2 - empty

I boot from HD0 and Grub comes up to choose either WinXP or Ubuntu.

Now I wanted to install Fedora 10 on HD2 which i chose at installation but it asks which drive to boot from, i chose HD2 but now when the computer boots, it goes straight to Fedora. I reinstalled Fedora on HD2 but this time i chose boot from HD0 but now i get the fedora Grub screen with XP and Fedora as options but I don't see my ubuntu OS. After a bit of googling, I added these lines to Grub from Fedora Grub edit

title Your New Operating System’s Name
root (hd0,0)
makeactive
chainloader +1

though i see the Ubuntu option now, i don't get anything when i choose it.

hope anybody can help... I guess the real question is how to triple boot a system with 3 hard drives.

Fedora installer doesn't recognize other installed Linux distros. Thats an annoying problem/bug of Fedora installer. It detects Windows OS without any problem though.

Boot up Fedora and mount / partition of Ubuntu. Open /boot/grub/menu.lst file of Ubuntu and copy first title block ( title, root, kernel and initrd lines. ).
Add that title block in Fedora's /boot/grub/grub.conf file.

if i install Xp, then Fedora, then Ubuntu, will I be ok?

While installing fedora you can avoid install GRUB, and later add entry in your existing Ubuntu GRUB.

triple boot is a easyiest without any additional conf and settings.

Thats correct. Ubuntu installer will detect both, Windows XP and Fedora.
