Dual-boot Ubuntu XP (sp2)

[Cecylia]

I have a machine with 2 different HDD.

HDD0: XP-SP2 installed on it (formatted NTFS disk)
HDD1: ubuntu 6.10 (hard disk formatted to ext3 + a swap 1GB)

Grub is installed on HDD1 and was slightly modified,,,if I boot windows starts HDD0 . if I boot grub HDD1 gives me the choice between Ubuntu and Windows ,,, BUT if I choose Ubuntu, it starts OK
whereas if I choose Windows it gives me an error message like "unsupported format executabe"

Is it because of NTFS?

how to develop a system that I can not re-establish in each update of one of 2 OS?

thank you in advance for your help

I have almost the same config (XP on a disk ntfs and Kubuntu on the other), and the PC starts without problem. You say "grub is installed on HDD1 and was slightly modified, are you sure changes?

[Cecylia]

on which disk is your grub? Do you have a fat32 partition to boot?

before the changes of the 2 choices grub (ubuntu vs xp) did nothing (wrong) ... a friend who knows a little linux changed my menu.lst (I think) to correct the target of choice ubuntu or windows (hd1, 0 -> hd0, 0 and vice versa, I think).

Now boot ubuntu but not windows from grub ... (no problem if I boot directly to disk ntfs)

my friend said that it may be because grub do not boot on an ntfs partition that is not on the same disc ... I see no pkoi?

Could you mail me a copy of your menu.lst, or other settings that I have to play for AC ... (like you)

or, as a last resort, can I replace ntldr by grub? (and how)
if so, should I upgrade each OS (gender transition to vsita or ubuntu 7.04 ...)

thank you again

As the disk on which I installed Kubuntu was empty, I let the installation do its patitionnement default.
The partition boot type ext3

The menu.lst file is a bit long for the entire post on the forum, I can send you in PM if you want. In the meantime, I post here the main lines:

Menu.lst 

# # 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. 
# 
default 4 

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

I changed the line "default 4" to boot by default on XP ... nobody's perfect

I do not know if you can replace by grub ntldr because I use Linux for too little time.
If as you do not already.

Normally, if you install Linux over Windows, the grub takes care of everything without touching ...
And with different distributions.
