Havent fully read the other thread but if there aint anything on your mandrake that you need to keep:

get a dos boot disk
from a:\fdisk /mbr
go into fdisk then and remove partitions of mandrake
reinstall mandrake
put XP + 2000 on the mandrake boot loader

OK, firstly ... you DON'T need to reinstall Mandrake.

All you need to do is to get a Linux boot disk and boot into console Linux. From there you can re-install Mandrakes boot loader into the MBR (Master Boot Record). I presume Mandrake is using Grub as it's boot loader.

Try booting to console using your Mandrake disk (or someother boot disk Toms Root Boot).

Then mount your linux partition (typing fdisk will show you the partitions) on /mnt.

Then chroot /mnt and your root mount point will become there.

From there you should be able to do a grub-install /dev/hda [presuming it's hda].

Change your /boot/menu.lst (I suppose it makes sense to have it in /boot considering it's read on boot) to point to the correct windows partition.

As I'm neither a Grub nor Mandrake user I'm only 95% sure of the above but I'm sure someone will confirm/correct it.

And remember if you bugger it up it's always 100% recoverable by booting from a DOS boot disk and typing:

fdisk /mbr

Or using your OS CD Recovery Console's fixmbr command.

The [OT] bit about windows:

The reason you're getting two windows boot options is that when you install over an existing version it preserves it's entry in the boot.ini. If you open boot.ini in notepad and remove the offending line then it will be fixed. (Remember to back up your boot.ini)

Typedef

Me in some other thread
Boot linux.
open a terminal
become root

type dd if=/dev/hda(whatever is your root) of=linux.bootsect bs=512 count=1

copy this file to disk.

boot windows, copy this .bootsect file to your root c:\ drive.

edit boot.ini

add an entry like this


code:

---

[boot loader]

timeout=30

default=multi(0)disk(0)rdisk(0)partition(NT partition number )\WINNT

[operating systems]

c:\linux.bootsect="Linux"

multi(0)disk(0)rdisk(0)partition(NT Partition )\Winnt="Windows Nt"

Behold the shoe... tis the end of all things

having awful difficulties with the whole thing.

I use rescue and it brings me to the command prompt

Then I use
--dd if=/dev/hda5 of=linux.bootsect bs=512 count=1

fair enough it copies the file to the current folder

Then I try to copy the file to the floppy
---no good, the folder is there mnt/floppy (I never hear my floppy even being accessed)

So I try and mount
mount -t ntfs /dev/hda1 /nt
not there so I try to create the folder


I have Knoppix 3.1 on disk, I use it and I can see all the partitions, and I try to access the linux one on hda5 but there is a lock on the folder. WTF?

How do I log in as a diff user? is it not, logout then login?

I'm a total know nothing, and I want my easy interface back!

Grr ...

This all stems from ****t microsoft over writing my MDR I suspect!

[EDIT:

Ok so I recompose myself and have decided to show u exactly what I did.

throw in mandrake (most up2date version), let it boot

-"F1" - pressed for more options
after a while
-Boot:
so I type
-"rescue"
then after a while a menu appears, so I choose mount your partitions under /mnt
-could not find your root device :-(
To which I reply Sh1te, anyway
next I am brought back to menu where I choose "go to console"
-[root@rescue/]#
so here I type in
-"cd mnt"
-"mkdir nt"
-"ls" - to check if its there and it is!
-"mount -t ntfs /dev/hda1 /nt"
-mount point /nt does not exist
WTF, I just made it
then I try
-"dd if=/dev/hda3 bs=512 count=1 of =/mnt/floppy/bootsect.lin"
-1+0 records in
-1+0 records out
but I hear no noise at all from the floppy and when I check under /mnt/floppy there still is no noise but the file is there!
I also tried the other one
-"dd if=/dev/hda5 of=linux.bootsect bs=512 count"
no joy, by the way those are too diff files - linux.bootsect and bootsect.lin but I guess that doesn't matter till I get to the editing of the boot.ini file!
