John, I can provide an alternative approach to Felix's reply, but whatever method you use you need to tell us what you are doing with the first drive, i.e., is your Windows "C:" partition on that drive and are you setting the machine up to primarily boot Windows and you want to boot openSUSE from there? Or do you want to have openSUSE's grub be the primary boot loader and use it to boot Windows on the first drive? Or are you using a bios on-the-fly boot device selection feature and want to boot off both drives? Or . . . ? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Hello: Felix gave you a detailed description. I only want to add that you might have to recreate the initrd image, as device names are occasionally "hard-coded" in the initrd (at least it happened earlier, not sure about 12.1). Have a look at this thread: http://lists.opensuse.org/opensuse/2010-01/msg00577.html Another thing I do is that I install on the MBR chain-loaders only. This can be either lilo or grub and links the real bootloader of the system which resides on the root partition's boot sector. I you use grub both for the chainloader and the OS system loader you need two grub configurations. Eg: /boot/grub/ dir with all grub files (menu.lst etc) for system boot /boot/grub-chainloader dir with all grub files for the chainloader. menu.lst in /boot/chainloader looks like: # Modified by YaST2. Last modification on Wed Jan 12 22:24:13 CET 2011 # THIS FILE WILL BE PARTIALLY OVERWRITTEN by perl-Bootloader # Configure custom boot parameters for updated kernels in /etc/sysconfig/bootloader timeout 8 gfxmenu (hd0,0)/boot/message ##YaST - activate default 0 title openSUSE 11.2 rootnoverify (hd0,0) chainloader (hd0,0)+1 title openSUSE 11.4 rootnoverify (hd1,0) chainloader (hd1,0)+1 title openSUSE 12.1 rootnoverify (hd1,1) chainloader (hd1,1)+1 You can install grub and grub chainloader from a running system by the grub shell (running as root): # grub

root (hd0,0) # sets root to first disk, first partiton; adjust according to your system setup --force-lba (hd0,0) (hd0,0) # installs grub boot loader to first disk, first partition, uses grub files (menu.lst, stages) in /boot/grub dir on first disk, first partition quit

The above defaults to /boot/grub dir. For the chainloader grub-dir you have to use the --prefix option in grub:

setup --force-lba --prefix=/boot/grub-chainloader (hd0) (hd0,0)

This means that grub shell will install grub in according to the files in /boot/grub-chainloader/, and not /boot/grub/ Of course you have to change "(hdx,x)" according to the system. (hd0) is the MBR of the first hard disk. Istvan -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
