grub load w2k on 2nd drive

[monocongo]

Hello,
Can someone help with using GRUB for duel booting into W2k from Linux installed on another drive. I would like to boot W2k on hdb from grub installed on linux hda.

The way it is setup now if I choose DOS from the GRUB screen I get this: "rootnoverify (hd0,0) chainloader +1 Error 13: Invalid or unsupported executable format" which is of course is just what it says in the /boot/grub.conf file, and it will not load. Below are my grub.conf and partition tables from fdisk.

Can someone please give me a clue what I should do to be able to also boot into W2k on the second drive from grub? Thanks very much for any insight!

chainloader +1 ## I choose to load DOS from the GRUB menue

I could be totally wrong here but I believe you have to have Windows on Primary Drive as Windows will not at all see Linux being there therefore just overwrites bootloaders. (Not sure what happens if it is already installed)

What is your setup? I.E which OS on which drive.

i woudl guess linux on pri. mas. and windoze on pri. slav. right?

im not entirely sure on grub syntax, but i think the line that says

rootnoverify(hd1,1) shoudl be either (hd0,1) or (hd1,0)

I think for a Windows machine (purely Windows machine) at C:\ is required but as this is the case using GRUB, it's different.

In W2K, does the machine see the drive (with WINNT) as D:\? If so, the GRUB syntax should be (hd1,0).

i'm not an expert at this but from what i see, you obviously have 2 HDDs. here's what i did to my grub.conf file. asked, read around with no definite answers, but everyone tells me only grub can do this - "tricking windoze" so that it would think it were the primary master - since windoze is pretty selfish and doesn't want other OS besides other windoze variants and needs to be prim. mas.. this works fine! mabe this could help if i'm not too late...

i THINK the windows must be on pri. master things was fixed in win2k/xp
not entirely sure tho, this is MS we're dealing with.

The problem not being able to boot W2k from grub doesn't seem to have anything to do with which drive I try to boot, or if W2k is on the same drive as Linux. I have 2 PC's with several dirves W2k is on same drive as Linux on this machine and I get the same "error 13" when trying to boot w2K. Setup as follows:
Device Boot Start End Blocks Id System
hda1 * 1 2416 19406488+ 7 HPFS/NTFS
hda2 2417 2429 104422+ 83 Linux
hda3 2430 2462 265072+ 82 Linux swap
hda4 2463 4865 19302097+ f Win95 Ext'd (LBA)
hda5 2463 4865 19302066 83 Linux
At the grub command line I have tried all different combinations of rootnoverify, map, chainloader, and makeactive and boot with hd0, hd1, 0, and 1 to no avail.

It believe it has something to do with the bootloader and the MBR. Linux will boot fine on all machines but W2k will not boot from grub, no matter the commands or arguments I user. Anyone know anything about the Bootloader and mbr???
Thanks for the replys.
