I know my initial mail is very long. Please read it completely. At first I have tried GRUB1, then I have tried GRUB2 with the Lucid package - no success yet. The autodetection of operating systems is better in GRUB2, so I would prefer to use the new version. But it does not work even though dmraid is recognized. The configuration seems to be ok, but I cannot boot.
With GRUB1 I had more success, but not with the partition order I chose because of a bug in the Windows XP SP3 Disk Management Tool. All details are in my post.

Thanks for your help,

André
