problem with creating multiboot with two hard disk and two OS

HI
Thank you for reading my post.
i read some posts and article about this subject but all of those article tips does not apply on my item

.

I have installed OpenSuse 10.2 and now i can not use multiboot feature and each time i want to go to the other OS i should change the boot priority of hard disks in my BIOS.
for example if i want linux i should make linux hard disk to be first boot and if i want windows i should go to bios and change the first boot to my windows hard disk.

I should say that i have two SATA hard disk

here is content of device.map this file is located in /boot/grub/

Code:

(fd0)	/dev/fd0
(hd0)	/dev/sda
(hd1)	/dev/sdb

here is the fdisk -l command output,

Code:

Disk /dev/sda: 200.0 GB, 200049647616 bytes
255 heads, 63 sectors/track, 24321 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   *           1        6374    51199123+   7  HPFS/NTFS

/dev/sdb6           19123       24792    45544243+   7  HPFS/NTFS

it is from when i boot the system with linux, so Linux hard disk is first boot in the bios.

here is content of menu.lst from grub directory .

Code:

I tried many options with title windows, for example i changes all 1 to 0 and 0 to 1, it had no effect.
it always say that NTLD missing and use ALT+CTRL+Del to reboot the system.

how i can add multiboot feature ?

thanks
