Dual boot problem debian-windows, strange case

test_goraz — Mon, 17 Mar 2008 18:37:31 GMT

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

255 heads, 63 sectors/track, 9729 cylinders

/dev/hda9 5115 9729 37069956 83 Linux

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

## ## End Default Options ##

....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.

...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.

Kind regards,

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?

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.

kind regards

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-

The recovery from backup boot sector is also described here-
