Gues what guys I did the similar thing without Super Grub
I can now boot XP,Vista,Mint and SuSe all
OSL2000 simplifies everything
I can now select the boot disk for Linux and then go to GRUb of Mint from ther I can select Mint/SuSe or go to Windows OS selection menu.
I just booted from live CD of Mint once and did some "SUDO GRUB"
Then ran setup(hd0) and it was done.GRUB installed on MINT partition.
If you boot suse and then do "SUDO GRUB" and setup(hd0), it installed GRUB on SUSE partition..
