This work also for win98? This is covered in a nice mini-howto.
(mauby Linux-NT-loader).
Let me call /dev/hda6 the Linux partition and /dev/hda1 the NT

1) from Linux (get mbr for hda6)

                dd if=/dev/hda6 of=linux.mbr bs=1c count=521

I installed mbr in /dev/hda6 using LILO:


2) boot your NT and point the file boot.ini

        C:\attrib -s -r c:\boot.ini

Put the file linux.mbr in the directory boot/ in your NT (transport
it with a dos floppy, from Linux).

Open the file boot.ini with notepad and change it to reflect something

       [boot loader]
       [operating systems]
       multi(0)disk(0)rdisk(0)partition(1)\WINNT="Windows NT Workstation ...
       multi(0)disk(0)rdisk(0)partition(1)\WINNT="Windows NT Workstation ...
       C:\BOOT\linux.mbr="Debian GNU/Linux"

Restore file permissions:
C:\attrib +s +r c:\boot.ini

At boot, i wish between NT, Linux and win98 in the same machine.
Ok, a this moment, I removed NT for space raisons ...

This is not wizard's matter: you can save MBR with:

                dd if=/dev/hda1 of=MBR bs=1c count=512

and restore it when you wish.


I'd like to conclude with a positive statement, but I can't 
remember any. Would two negative ones do?       -- Woody Allen
