dual boot with 2 hard disk
However, if I have installed Win2k into the first disk (IDE) and Linux 8.) into the second disk (SCSI), how could I dual boot from the NT OS loader?
I've tried modifying boot.ini like:
scsi(0)disk(2)rdisk(0)partition(1)="RH Linux 8.0"
but it didn't work.
FYI, my PC doesn't allow me to choose which device to boot from.
Thanks in advance.

Re: dual boot with 2 hard disk
Why don't you install grub bootloader into MBR of first partition? grub can boot win2k just fine with an entry like this:
title Win2K
rootnoverify (hd0,0)
makeactive
chainloader +1
I am booting like this for ages ...

Re: dual boot with 2 hard disk
$ dd if=/dev/hda of=mbr.img bs=512 count=1
Then you can restore it later with
$ dd if=mbr.img of=/dev/hda

Re: dual boot with 2 hard disk
If I were to boot both OS using GRUB, how could I relocate my grub loader to MBR of first IDE drive without reinstalling it?
I have tried
dd if=/dev/sda of=/dev/hda bs=512 count=1
but it didn't work!
Would that means we could not load both OS in 2 hdisk using NT osloader ?
Thanks.

Re: dual boot with 2 hard disk
I run severals PC, mixing W2K - NT4 - Linux and IDE-SCSI drive.
Usually I use Lilo, but I think It will also work with Grub or others boot loader.
I don't know how you've create you partition, usually I do things like this :
Frist HDD (bootable HDD, usually IDE):
- frist partition: FAT 16, size=10-20 Mo, ONLY for multi-boot
- second partition: NTFS or EXT2, for OS
second HDD (not bootable HDD, usually SCSI):
- NTFS or EXT2 partition, for OS
Then 3th 4th ... HDD for DATAs.
After what I install NT4-W2K whit a NT4-W2K boot loader in the bootable MBR (if destroyed, use the rescue/recovery console from a bootable W2K CD-Rom and the fixboot / fixmbr commands or with the linux command dd if=... of=...).
Then I install a Linux system (for me a Debian 3.0, but it work with other like Suse, Mandrake...) WITHOUT a boot in MBR, but with the boot in root-partition (/).
Then a litle Linux instruction like thoses ones to copy the linux boot sector in a file on the fisrt (bootable) partition :
# mount /dev/hda1 /mnt/dos16
# dd if=/dev/xdxx bs=512 count=1 of=/mnt/dos16/bootsec.lin
where xdxx can be: hda2, sda1 ...
Then under NT4-W2K, here is the point you search:
update boot.ini, adding a line like THIS one :
c:\bootsec.lin="linux"
and NOT like this one :
scsi(0)disk(2)rdisk(0)partition(1)="RH Linux 8.0"
because the linux boot sector MUST be load like if it was a W9x system and NOT a NT-like system, or using a syntax like
You will perhaps encounter other problems:
check if you SCSI card power-on and spin-up your SCSI HDD before the system try to boot on it.
On an Adaptec card it's easy by the integrate bios manager, access by hitting F6 during the card check-up.
If your first (bootable) partition on the fisrt (bootable) HDD is a NTFS one I'm not sure it will so easy, but try it and report me if success or failure. For that point and because all system can access FAT16 I allway use a litle FAT16 partition on my boot-HDD.
Good luck.
