Hi,

I just reinstalled WinXP and need to edit the grub/menu.lst file in order for it to be able to start XP again.

There are some guides on the net, but either I'm to thick or I do something wrong or I don't understand correctly or all three....

Please help

You need to change the line that says

default 3
to

default 6
You need to count from zero every time that 'title' occurs. Where you've commented out title (and kernel etc) with '#' you need to remove the # as you want to be able to get to the old kernels and memtest in case you have problems with the new kernel (that is updated operating system).
Your new menu.lst should read as follows:

# menu.lst - See: grub(8), info grub, update-grub(8)
# grub-install(8), grub-floppy(8),
# grub-md5-crypt, /usr/share/doc/grub
# and /usr/share/doc/grub-doc/.

## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not use 'savedefault' or your
# array will desync and will not let you boot your system.
default 6

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout 10

When you edit the menu.lst file don't forget to use 'sudo'.

Thamks.

My problem was actually, that I can not start WinXP again. So the fault must be at the end of the file.

The other entries I crossed out in order to make my list smaller - I doesn't have anything to do with the ability to strat WinXP.

I stand to be corrected

i m going to dual boot windows - intrepid in few minutes, and i read about changing this list as u did, the only difference i can see is this 2 lines:

map (hd0) (hd1)
map (hd1) (hd0)


may the root values (hd1,0) is wrong also, as it was said in this thread (http://ubuntuforums.org/showpost.php?p=6527371&postcount=1):


if that does not work on re-boot try “hd0,0 or hd0,2” and so on until it works.

It may be worth booting into Ubuntu 8.10 and running the following in terminal

sudo update-grub
That may fix the windows problem on the second (IDE ?) drive. If you are running windows on the first drive you may not need the map commands.

Into my arms....root values should have been (hd1,1). Thank you!

That had me in sixes and sevens...I certainly wasn't looking forward to reinstall Windows again, get all the drivers on, anti virus software....etc etc.

Thanks for everybody putting in an effort to help!
