Hi, I want to install SuSE Linux on a system with Windows XP on 2 HDs in RAID 1 (mirror) and the 3rd HD for back-up. It is possible to make room on the 3rd HD for SuSE, but the MBR seems write protected. So no dual boot menu. Any tips?

You could boot into SuSE from Windows. It is possible, but having to boot Windows takes away from the experience. You would need to install grub in the Linux partition instead of the MBR. I believe there are howto's available. One thing is I think Linux may not see the drives running on the fake raid of the main board unless it is supported.

Thanks, I ordered the ultimateboot cd. ultimatebootcd.com led me to Smart Boot Manager on btmgr.sourceforge.net which promises booting from cd-rom, but I can't find in the docs how to create this boot cd.

Write protection of the MBR could be done in the BIOS. Check settings for it.

The MBR could be on the 3rd HD (not write protected). How can I find where the MBR is located? I allways thought it to be the 1st HDs 512 bytes ... I'm going to replace SuSE 10.1 with 10.3 - but before I let SuSE change the MBR on the 3rd HD (assuming it is there) I want to know how this can be undone in case Windows does not boot anymore.

Every HD has an MBR. Yes, it is the first sector. Which one is used to boot, depends on the bios ("boot order: C, A", etc).

To avoid confusion I restrict the term MBR to the first sector of the HD that contains machine code executed to boot. A first sector of another HD I'd call Partition sector or Sector 0.

The term MBR for a Sector 0 that contains no boot code, at least no code that is executed to boot, is a misnomer. Only the R makes sense.

But the first disk is defined by the boot order of your BIOS. Any disk can be the first disk. And every disk has an MBR. It is only the MBR of the first disk, as defined by the BIOS, that is used to load the boot code. -- Joe Morris Registered Linux user 231871 running openSUSE 10.3 x86_64 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Ah, so the first disk, as defined by the BIOS, may not be the one which I'd call first, the Master Disk at the end of the primary flat cable. In my system, without RAID, there is no ambiguity which one is first, it has WinME and YaST Partitioner lists it as hda (SuSE 10.2) or sda (10.3). Next week I get my hands on the system with 2 disks in RAID 1 for WinXP and a third disk with a SuSE partition. Then I can see which one is defined first by the BIOS and how YaST Partitioner calls it.

Since you should be able to setup the BIOS, you still decide which the BIOS boot order calls disk 1.
In my system, without RAID, there is no ambiguity which one is first, it has WinME and YaST Partitioner lists it as hda (SuSE 10.2) or sda (10.3).
It isn't ambiguous, it is always the same order you set it up in the BIOS.

If it has a boot time boot menu option (i.e. F11 or F12 usually), you can change at boot which disk is the MBR the BIOS will look to boot from. That is why I said before you could unplug those 2 disks, install 10.3 without fear, install GRUB into the MBR of the 3rd disk, and decide with the BIOS boot menu which system you boot. -- Joe Morris Registered Linux user 231871 running openSUSE 10.3 x86_64 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

SuSE 10.3 KDE / K Menu / KDE Help Center / openSUSE Documentation Reference - III System - 12.1 The Linux Boot Process
I use GNome, and the "khelpcenter" (version 3.93.00) shows a blank, complains of no index, asks: build one? fails ans hangs, asks again. You mean this: /usr/share/doc/manual/opensuse-manual_en/manual/cha.boot.html#sec.boot.proc Boot Loader. The first physical 512-byte data sector of the first hard disk is loaded into the main memory and the boot loader that resides at the beginning of this sector takes over. The commands executed by the boot loader determine the remaining part of the boot process. Therefore, the first 512 bytes on the first hard disk are referred to as the Master Boot Record (MBR). The boot loader then passes control to the actual operating system, in this case, the Linux kernel. More information about GRUB, the Linux boot loader, can be found in Chapter 13, The Boot Loader. Well... while this is true, it is confusing if it leads you to think that the MBR is only the one from the first disk. - -- Cheers, Carlos E.

Not 1st, but each
I'm going to replace SuSE 10.1 with 10.3 - but before I let SuSE change the MBR on the 3rd HD (assuming it is there) I want to know how this can be undone in case Windows does not boot anymore.
Since Windows does not boot from the 3rd HD (assuming), it would have no effect, BUT I would verify during install EXACTLY where it plans to install GRUB. If you wanted, especially if your BIOS supported a boot menu, you could just disconnect the WINDOWS disks, install 10.3 to the 3rd as planned, then afterwards, you could use the BIOS or the boot menu to determine which OS you will boot.
I'll also burn a boot CD according to the openSUSE documentation section 13.5. I know how to do this on a system without RAID, but on the system with the 1st and 2nd HD in RAID, in menu.lst
