Did you do something like that? Could you explain us how did you install windows and then Linux, in that time did you do some change in hard disks?

A reason that could explain your problem, is that GRUB is not recognizing correctly the order of the hard disks, one more thing could you post the content of the file /boot/grub/device.map:

Code:

cat /boot/grub/device.map

Finally can you post the content of the file C:\boot.ini, in your Windows system?

Hope with that info we can give you a solution.

I'm using sata drives. I don't think they need to be slave or master.

I installed windows on one hard drive. Then I plugged in the other hard drive to the motherboard and installed suse10.

I'm not at my home computer. I'll post the output shortly.

It's very likely that GRUB is not able to recognize the adequate partition when trying to boot Windows, this could have happened when you install the other SATA hard disk. The order of the disks in the Bios may also have been altered. You can see the order of the hard disks in the file /boo/grub/device.map.

I suggest you to install again GRUB, you can use as a reference this excellent tutorial about GRUB: http://en.opensuse.org/SDB:The_Boot_Manager_Grub

Remember this when reinstalling GRUB:

- Install GRUB in the MBR (Master Boot Record) of the first hard disk.
- If you don't have Windows in the first hard disk, use the map command, as previously posted.
- Check carefully the OSs and the partitions where they are installed when YaST recognizes them

Hope this helps.
