Hi JFX, You've made an amazing app. It's really nice. I do have a question: how can I install windows srv 2008 r2 on a computer that already has XP installed and have two operating systems running together? I tried couple times, but it won't work. Here is what I do: I chooe partition D as the installation destination for win srv 2008 r2 when XP is on partition C. I do notice that the PBR checkbox is not green when I hit the setup and choose bootsect option (also've tried bootice) to update the boot code, and of course the option to detect OS already installed on this PC. After a reboot, my computer won't go to sysprep phase. It displays the boot selection to XP and win srv 2008 r2, but when I choose 2008 r2, an error happens, saying I have to repair boot xxxxx (I can not really remember) using a windows CD/DVD. Can you pls tell where I did wrong and how can I do it correctly? Thanks.
