Dual boot into W2K from GRUB

duel boot into W2k from GRUB

I have W2k on same drive as grub and linux as follows:

Device Boot Start End Blocks Id System
hda1 * 1 2416 19406488+ 7 HPFS/NTFS
hda2 2417 2429 104422+ 83 Linux ## grub is here
hda3 2430 2462 265072+ 82 Linux swap
hda4 2463 4865 19302097+ f Win95 Ext'd (LBA)
hda5 2463 4865 19302066 83 Linux

I get the same "error 13, invalid or unsupported executable format" as when I was trying to boot W2k on a defferent drive as grub. I've tried all combinations of rootnoverify(hdX, X), map and chainloader. makeactive and boot at the grub command line to no avail.

It must have something to do with the bootloader and mbr, but don't have a clue what to do about it. Can anyone help??

Thanks very much!

 

Yes, sounds incredibly easy. This is basicly what I've been doing, editing menu.lst or from the grub command line. On two machines, one with two drives, W2K on one and Linux on the other... another machine with both OS on the same drive.
The return is that it gives me the lines I entered into grub with and error 13, and will hang.
I believe it has something to do with the MBR. These drives worked fine in another machine, wish I knew what was different on that other PC.
The debian how-to is the best I've seen yet. Thanks
