Can't boot Windows Xp from GRUB


Hello,
I'm a newbie in informatics and Linux.
I'd deleted a disk partition with Ubuntu in my machine and GRUB was installed there.
Since this, I had been unable to load GRUB.
I restored it using fdisk -l and then I updated menu.lst and fstab and finally Ubuntu runs ok from GRUB. (I'd installed my mistake linux in two different disk partitions).
However, I have another partition with FreeDOS and Windows Xp and both OSes doesn't boot.
When I try to run FreeDOS a message apperas telling me there is no kernel and when I try to start Windows appears the login screen with the Windows logo for an instant and then a blue screen and my laptop reboots.
I access both Windows Xp and FreeDOS through a sub menu inside FreeDOS option in GRUB selection screen.

This is my menu.lst output:
Code:
# menu.lst - See: grub(8), info grub, update-grub(8)
#            grub-install(8), grub-floppy(8),

OK - lets look at the code...

fstab only shows root and swap - presumably for ubuntu. What is the output of fdisk -l?

Code:
title		Ubuntu 8.04.1, kernel 2.6.24-19-generic
root		(hd0,5)
... this is telling me to expect ubuntu boot directory on sda6, fstab reports ubuntu root on sda7 and does not display sda6.

Code:
# This entry automatically added by the Debian installer for a non-linux OS

title		FreeDOS
root		(hd0,0)

... that root line should read "rootnoverify" - AFAIK: FreeDOS does not have a unix kernel. Is FreeDOS really in sda1? Windows usually likes to be there.

You have two sets of entries for Ubuntu, in two places. If you have only one installation of Ubuntu, delete the entries which do not apply.

There is no entry for Windows in the menu.lst supplied.

The information supplied is not consistent. Please correct this.

I use Ubuntu 8.04 Hardy Heron.

I'm sorry, I used fdisk -l in order to know what partition I have Ubuntu installed. I have it installed in hd(0,5).
Then I typed...
Code:
sudo grub 
root (hd0, 5)
setup (hd0)
quit
...in order to make GRUB work again (GURB had error 22). The message before type this was "GRUB loading, please wait... Error 22".

This is my fdisk -l output:

Partition table entries are not in disk order
Quote:

I bought my laptop with both Windows XP Professional and FreeDOS installed so I assumed Xp and FreeDOS are located in the same disk partition. I'm a newbie in informatics and I can be wrong.
However I don't mind if I cannot run FreeDOS again, actually I've never used it. I'm principally interested in be able to use Windows again.

Quote:
Quote exact message.
The exact message when I try to load FreeDOS is "loading FreeDOS No KERNEL SYS".

Quote:

The blue screen appears for a very small amount of time and I'm totally unable to read it but there are some text in it and a row of numbers in the last line. I'd never got this blue screen.

I will change root for rootnoverify and I will post what happens.

I will delete them and post menu.lst output. I dunno how ro make a correctly a Windows entry.

I've made the change but it have not solved the problem and when I try to use FreeDOS appears the same message again ("loading FreeDOS No KERNEL SYS").

[url=http://en.wikipedia.org/wiki/Blue_Screen_of_Death]This is what a BSOD looks like.[/quote]

Looking at fstab -l output, sda1 a fat32 partition, which would normally be Windows XP. The following entry should boot WinXP happily.

title Windows XP
root (hd0,0)
savedefault
makeactive
chainloader +1

Though I'd normally prefer a rootnoverify but, apparently, grub is smart enough these days.

savedefault is only needed if you want XP to be the default boot option. Recommend you try doing your routine work in Ubuntu and do a special boot only for those annoying 'dows-only things. It will quickly become a preference. (I take it there is no problem booting and running ubuntu?)

The puzzle is that this entry is identical to your one for freedos. (The title makes no difference). That GRUB entry will set the root partition to sda1 (C:\) then pass the boot process to whatever is there to catch it.

I suspect there is a bootloader there which would normally allow you to choose between XP and FreeDOS - is this correct?

You're right there were a bootloader (NTFS) in Windows and FreeDos partition. So the problem was in NTFS (it was not a GRUB issue).
I've had to format the partition and reinstall Windows.
Thanks everybody.

Niggle - NTFS is not a bootloader. It's a file-system.
But... well done on your solution. I think...
