    Re-configure the OTHER GRUB loader...

This way you have the two original systems booting normally and only need to add PCLos to the menu.lst of Ubunu.
    .
    I found no solution to the earlier GRUB mod. So I'm tryin' now to import the PCLOS loader into the Ubuntu GRUB (with XPPro), but alas, no success thus far.

    PCLOS disk is now mapping as hd2. From GRUB cli, I did find /boot/grub/menu.lst. It returned 3 entries: (hd0,0[Ubuntu]), (hd2,0), and (hd2,6).

    Help?

    You need to show us

    (1) The menu.lst of PCLos

    (2) The output of terminal commands
    Code:
    sudo su
    grub
    geometry (hd0)
    geometry (hd1) 
    geometry (hd2)
    No everybody is aware of your setup. Since you are able to boot 2 out of the 3 systems you should freeze the disk order from now on and concentrate on working with the Ubuntu's Grub.

    EDIT:
    It has booted PCLOS without a problem. Thanks for helpin' out there saikee!

    Now, if I can just get FC8 back onto the disk with PCLOS...

    PCLOS' GRUB:

    Code:
    timeout 10
    color black/cyan yellow/cyan
    gfxmenu (hd2,6)/usr/share/gfxboot/themes/pclinuxos/boot/message
    default 0
    
    title linux
    kernel (hd2,6)/boot/vmlinuz BOOT_IMAGE=linux root=/dev/hdf7  acpi=on resume=/dev/hdf5 splash=silent vga=788
    initrd (hd2,6)/boot/initrd.img
    
    title linux-nonfb
    kernel (hd2,6)/boot/vmlinuz BOOT_IMAGE=linux-nonfb root=/dev/hdf7  acpi=on resume=/dev/hdf5
    initrd (hd2,6)/boot/initrd.img
    
    title failsafe
    kernel (hd2,6)/boot/vmlinuz BOOT_IMAGE=failsafe root=/dev/hdf7  failsafe acpi=on resume=/dev/hdf5
    initrd (hd2,6)/boot/initrd.img
    
    title windows
    root (hd1,0)
    map (0x81) (0x80)
    map (0x80) (0x81)
    makeactive
    chainloader +1
    I copied and pasted the 'RED' entry into Ubuntu GRUB...

    buccaneere,

    The easiest way to multi boot as many distros as you want is during installation you point a gun at the installer's head and instruct it not put its boot loader in the MBR but inside its root partition. If that root partition is say (hd2,8) then the Grub commands to boot it are
    Code:
    title whatever OS in (hd2,8)
    root (hd2,8)
    chainloader +1
    or if the distro has Grub the following also works
    Code:
    title whatever OS in (hd2,8)
    root (hd2,8)
    configfile /boot/grub/menu.lst
    The above is all you need to boot as many distros as you care to install.

    Believe me there is nothing difficult in booting with Linux. You can write your own menu.lst even before you install all your operating systems. "Chainloading" is the easiest and laziest way. It is exactly how a MS Windoze is booted so why not use it.
