There are probably a couple of ways.

1. make a grub boot disk (man grub)
2. download 'Super Grub Disk", about 3 MBytes

Both allow you to boot off the /boot/grub/menu/lst of your second
partition and wont do anything to your mbr

I am really not sure what the problem is, if you do a #grub-install
hd0 you will put the grub back on the mbr.

If you want your windows selectable, I thought that it was only a
matter of adding that to menu.lst

The Super Grub Disk also 'fixes' windows boot sectors but I am not
into that, yet.
