Adding OS to GRUB from non-ubuntu HD

Asked by Viknesh

I have 3 hdds on my computer, one with Ubuntu (Studio) and two others with winxp. I wish to use WinXP as my main OS, and so I made the hdd with it the first on the boot list according to the BIOS. However, when I boot, I still get GRUB. Since GRUB is not giving me an option to boot from the XP hdd...Well, just...how do you do it?

To boot from that disk it needs to be bootable.

In any case, you can boot from it from grub, but you need to modify your /boot/grub/menu.lst file to add an entry for the new disk. This is an example:

title My beloved HDD
root (hd0,0)
savedefault
makeactive
chainloader +1

You need to modify (hd0,0) to match the hd you want to use.
Here is a link to the grub manual if you need an handy reference:

Can you help with this problem?
