Can Grub start Windows XP from "other" partition

[Ulf Zibis]

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
