I have a boot VHD that is working good. I need to execute various commands before booting the VHD. Is there an easy way to do this? Or should I look into modifying a boot loader (GRUB?). I need to copy the VHD before it boots and then start/boot it. As an alternative solution, is there a way to run a read-only VHD that automatically writes any output needed to a temp partition? I want to boot into a clean base environment each time. This is using Windows 7 Enterprise. Any help or pointers are appreciated. I have Google'd the heck out of this and was not able to find anything specific to my goals.
