Please any body can help how to dual boot from dual harddisk.
i have installed window XP in one harddisk and install open suse 11
in another harddisk.How can i can boot the two operating system
which is in different harddisk.

U have GRUB for that right?
Or am i missing something?

Assuming you have Windows on the first hard disk, when you installed openSUSE, it should have overwritten the MBR on the first hard disk with a pointer to GRUB on the second hard disk which should then have offered you a menu.

It sounds as if some part of that process did not happen.

Please describe in more detail how you installed OpenSuse, with particular reference to:

  • whether you were switching in the bios which drive to boot
  • whether it was an internal or an external drive for openSUSE
  • which partition on the first drive has the windows operating system
  • and whatever else you think might help us

Also please paste here the contents of /boot/grub/menu.lst (use sudo cat /boot.grub/menu.lst to display it)
and of the file /etc/grub.conf (use cat /etc/grub.conf to display it)
And please post the response you get in a console to this command:

sudo /sbin/fdisk -l
