Apologies for posting this here, but Bootland is a bit daunting I want to temporarily install XP a second time to my laptop. Using DD I've created a new primary NTFS partition immediately after the existing XP boot partition, but if I just go ahead and install XP to this partition I will get a Microsoft style dual boot which I don't want. I use Grub4DOS as boot manager, and want to use its config file to hide each XP when booting the other. I know how to do this, but before going ahead with the install can I add hide (hd0,0) to fool the installer? If this is OK I know how to restore my MBR to get Grub4DOS back. EDIT - forgot to add that after adding that line I would reboot to my VistaPE partition in order to get the XP partition hidden.
