Nah, he doesn't want to format his new notebook, but his old one, and there's no stuff to backup.
I don't need anything in my old laptop so no need to save.
But tell me, do you want to reinstall XP on the old notebook? If so, there WILL be a screen where you have to choose a partition to install Windows. Press the key to delete the partition (for us Germans it's the "L" key I think (L -> Löschen: delete, erase)), then choose it, and take the "Format with NTFS file system" option.
