linux on second disk

[Héri Tamás]

Hello all,

I have the following question (short):
Is it possible to boot an installed (Debian) Linux (root 
partition resides on /dev/hdb2) from the second disk by 
GRUB?

Long:
I have three disk in my newly built machine. 

-- on the first (hda, or hd0), a WinNT is installed (I did 
it from boot floppies)
-- on the second (hdb or hd1), a Debian 2.2r5 is installed 
(from CD), with root partition in /dev/hdb2
-- I want to install Win98 to the third (hdc or hd2).

Is it possible to start all OSes just by setting the boot 
sequence in BIOS (I mean, I can set boot from HDD-0, HDD-1 
etc.) ? For complete safety I want the first disk's MBR 
untouched. How shall I install GRUB to place it's stage1 to 
(hd1) ? 

I tried the following install command:

grub> root (hd1,1)
grub> install /boot/grub/stage1 d (hd1) /boot/grub/stage2 
p /boot/grub/menu.lst
grub> quit

After that, and setting BIOS to boot from HDD-1 (second 
disk), the system stops after Power-On-Self-Test.

However, from floppy I can boot everything from everywhere 
(Linux from /dev/hdb2, WinNT from /dev/hda):

grub> root (hd1,1)
grub> install /boot/grub/stage1 d (fd0) /boot/grub/stage2 
p /boot/grub/menu.lst
grub> quit

Thanks in advance.
