Hi Leslie again,
thanks for your effort to describe your configuration.
I'm afraid, my problem is very different from yours.
You have only 1 Windows in your configuration, but I have 2.
I guess, you have installed Windows in some fix partition and have never changed it. So the Windows
inside will see this partition as e.g. C: and that never changed.
In my case the "old" Windows-installation was originally installed in partition
sda1 as C:
Now I have copied that partition to sda5 with GParted and did a new
Windows-installation in sda1.
Grub 2 now shows 2 Windows operating systems in it's start menu after update-grub from Ubuntu in
sda3. (sda2 is occupied by the ThinkPad recovery partition)
When booting with Grub 2 into sda5, I'm afraid, the "old" Windows installation will see the sda1
partition as C: and sda5 as D: so it would use and probably change files in sda1 while referring to
path C:\....
Before I try this, I would be happy if someone could insure me, that Grub 2 will hide partition sda1
when booting Windows from partition sda5 to prevent a corruption of the data in sda1 while first
booting.
Can somebody give me information about that risk and hopefully some hints how
to prevent from?

This is my process.
1) My disk has Debian, Fedora16, Ubuntu, Windows and Fedora 18 (test). If I boot without doing
anything, it is the Debian grub.cfg file that takes control.
2) When an update comes for either of the distributions (Fedoras, or Ubuntu), it is their own
grub.cfg that gets updated. I need to transfer that update to the Debian grub.cfg
3) When I see this happening I boot into my Debian system
4) I log onto that Debian system as root and do a grub.mkconfig >/tmp/grub.cfg
5) I review that grub.cfg to reset the default to 7 (it is a field near the beginning of the file)
(Menus are Counted beginning with zero). I also remove more than two generations of linux entries
in this grub.cfg and save the file.
I change to the /boot/grub directory and do a cp grub.cfg to grub.bak
I then copy the /tmp/grub.cfg to /boot/grub. (replacing the Debian grub.cfg)
I reboot, and see all my updates. in the initial menu selection screen.
grub.mkconfig will also recognize all windows operating systems

Hi Leslie,
that sounds good, thanks for your quick answer.
Just to avoid some bad experience on my existing installation, are you
really sure, that
Windows will see the other not 1. partition, from which it is started, as
C:, even from a
logical partition?
Again thanks,
Ulf

YES.
When you execute grub2, it surveys all the disks and all the partitions and
lists all the
operating systems in a list. You may set the default to the operating
system of choice.
The command is grub.mkconfig (or grub-mkconfig) put the output of
mkconfig to /tmp ans use
an editor to review it

Hi,
I have an old bad running WinXP installation, which was installed on
partition 1 as C:.
Now I want to move this installation to another partition and make a
fresh WinXP
installation on partition 1.
For some reasons, I want to have the possibility to run the old
installation later. I
believe, that I can run it, if I manually "hide" the 1. partition and
mark the 2. as
active/boot, so Windows will guess the 2. partition as C:.
I Grub smart enough to do that for me when booting the old Windows
partition from the 2.
partition?
Ideally I would like to move the old WinXP installation to a "logical"
partition. Would
that also work?
So my preferred partitioning would be like:
Primary partition 1: new Windows XP installation
Primary partition 2: Thinkpad Recovery (physically at the end of the of
the harddrive)
Primary partition 3: Ubuntu
Extended partition 4:
Logical partition 5: Ubuntu swap
Logical partition 6: Data
Logical partition 7: Backup
Logical partition 8: old bad Windows XP installation (Copy from
originally C:)
Thanks for hints,
-Ulf
