FDISK /mbr

[M.Arthur]

Mandrake 8.1
Is there a FDISK command?
I need to use FDISK To recreate my MBR as unable to boot to drive 1 C: windows.
As a result of reconfiguring default lilo changed to GRUB
Mandrake works fine but now unable to boot up C: drive D: drive OK.
Have tried DOS floppy FDISK/mbr but message reads
The Master Boot record Code has NOT been upgraded
Any help with this problem

You could try editing the menu.lst file and add lines to it to allow you to boot windows. That is a lower case ' L ' in ' menu.lst '. I added these lines to mine:

title windows
root (hd0,0)
makeactive
chainloader +1


The hd0,0 means that the partition windows is on is hda1. I believe that is where yours is probably located. So, this code should work for you. I don't know why the command fdisk /mbr didn't work for you.

If you use fdisk /mbr you will delete the MBR entries. What you need to do, is edit (in case lilo) lilo.conf and put other image for windows
But if you use grub i can't help you, because i never work with it.

If all else fails, try using the fdisk from DOS version 7 and above (Win95 - Win98SE).

After clearing the mbr as above I would recommend booting to your windows partition and using loadlin.exe (see mini-HOWTO) to boot linux. This means that you can put your linux boot partition anywhere on your drives and your mbr doesn't get altered. A better choice all round.

To choose what to boot put a menu at the top of the config.sys & autoexec.bat. You can do this becuase (believe it or not) windows supports a boot time menu you can use to boot to another OS (although I would imagine Billy didn't intend this use for it).

LILO doesn't necessarily have to install on the MBR. I don't install it there. Just make sure you have a bootable Linux partition and then set LILO to boot from there.
