Dual boot for 2 HDDs

I have Opensuse 12.1 on my HDD1 (500GB) and my WinXP on HDD2 (80GB). I want to dual boot in to two OS’s respectively. So basally when I plug both HDDs it’s only booting from WinXP, How do I configure the GRUB or bootloader to make this support dual boot.

Thanks,
GT540.

Were the OS’s installed whilst only 1 HD was connected respectively?

Either switch the Boot order so the SUSE HD is first in the boot order in the BIOS
or report the content of

su -
cat /boot/grub/menu.lst

we can go from there

If I had two independent hard drives, one that boots openSUSE and the other that boots Windows, you need to keep both plugged in and go into your BIOS setup and select the openSUSE drive to boot up first. Then, you can add an entry in your Grub OS selection menu to run Windows if you want. You can then use findgrub to tell you the correct menu.lst entry for openSUSE 12.1 and strictly speaking, openSUSE 12.2 and its grub 2 would find it automatically.

Thank You,

Hi thanks for the reply I configured the GRUB (/boot/grub/menu.lst) and it’s working now.
