I went ahead and experimented with Grub2 as boot menu entry just to see if it would work. I didn't think it would be so easy, but it was after finding a how-to that gave simple instructions.
I have two hard drives (non-RAID), XP is installed on the first hard drive. I use my second hard drive for Pardus, my main distro, and playing with other Linux distros. I installed the other Linux distros first, allowing each to install Grub to their particular root partitions. I installed Pardus last, and allowed it to install its Grub on the MBR of the first hard drive, sda. That done, I had a nice Pardus 2011 Grub menu to boot into.
I then followed
this how-to from Just Another Blog on the Net, to use a live disc to re-install Grub2 to the MBR. I decided to use moonOS, which has a Ubuntu-based Grub2 entry on root partition, sdb13.
partial output of my fdisk -l (yes, I have too many os's I am testing

)

I started the moonOS live disk and opened terminal and did according to instructions:
sudo mount /dev/sdb13 /mnt (click 'enter')
Then I ran the Grub re-install command according to instructions:
sudo grub-install --root-directory=/mnt/ /dev/sda (click 'enter')
Exit from terminal and reboot. Boot into the distro that has the Grub2 menu entry you just re-installed, and open terminal:
sudo update-grub2 (click 'enter')
and it will search for other operating systems and add them. Reboot, and I can successfully select Pardus from Grub2 menu and boot into it.
This is Pardus entry in moonOS' grub.cfg file:
menuentry "Pardus 2011 [2.6.37] (on /dev/sdb5)" {
insmod part_msdos
insmod ext2
set root='(hd1,msdos5)'
search --no-floppy --fs-uuid --set (xxxxxxxxxxxxxx)
linux /boot/kernel-2.6.37 root=UUID=(xxxxxxxxxxxxxxx)
resume=/dev/sdb9 quiet splash blacklist=nouveau
initrd /boot/initramfs-2.6.37
I have since re-installed Pardus Grub using
Pardus Wiki How-To since it is my main distro and I have more confidence in Grub Legacy. My hard drive says, "Leave me alone!" and I will do just that.
