Dual boot problem debian-windows, strange case

Hi all, I really your help, just to see what I can not see.
I have installed debian/lenny in dual boot with win/xp ( many times in last 3,5 years ).
Today I installed it again and during installation I got an message "...it seems that it is only os ...blala " but I said ok, it is not problem I will set up it in /boot/grub/menu.lst
I did it many times before.

But today I have some strange situation.
fdisk -l has output:

fdisk -l

Disk /dev/hda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders

in my /boot/grub/menu.lst I have ( last lines regarding booting system ... )

....The part regarding windows I added...
and now when I want to boot into windows I get and message " Grub loading stage 2 Read Error " ...and just hung there :(.

I tried many " tricks", googled, used live cd to install grub into hd0, the grub is installed during installation into MBR.

Please if some one know what to, you will help me a lot if you write it here.

With regards,

I don't see why you are using map commands.
Do you have multiple hard disks installed?
The rest of your posting looks like you only have one disk, hd0.

Re: Dual boot problem debian-windows, strange case

...just experimenting, I read it on some mailing-list. I have just one disk hda.
Without map command I also cannot boot into into Win/xp
I installed many times in dual boot linux and windows, but this is very strange for me and I do not know what to do.

Re: Dual boot problem debian-windows, strange case

You certainly should NOT use the map commands for your configuration.
Are you getting the same error message when booting the XP partition without the map commands?

Re: Dual boot problem debian-windows, strange case

Thanks for your answers.
I tried and without map commands, and in that case I got after chosing to boot win/xp just flash showing following "

Booting 'windows/xp'
rootnoverfy (hd0,0)
makeactive
chainloader +1

Grub loading stage 2.....

And after this message is flashed everything is returned to grub menu, to starting point, and after grub-timeout linux is ready for boot.

I tried with(out) map commands but I cannot solve it to boot into win/xp. This is strange to me, because I did the same proces many times, and everything was simple, to be honest install system is not anything difficult, but sometimes it can be.

Your symptoms sound a lot like this discussion-
http://ubuntuforums.org/archive/index.php/t-91050.html

If your most recent install actually wrote grub at the start of the first NTFS partition then you would chainload right back into grub.

This posting may have a cure. I haven't tried it myself-
