I am aware that there exists tools that can change the mbr of the drive so that it can boot up multiple operating systems such as the Windows XP installer, Windows 7 installer, Windows PE-based live environment, and a linux live environment with software like this: http://www.msfn.org/board/topic/120444-how-to-install-windows-from-usb-winsetupfromusb-with-gui/
But all these things are made possible via grub4dos or some variant of that. How would I access the uefi boot options from the Windows 7 installer, for installing in UEFI mode? Some linux distributions such as Ubuntu now also support UEFI mode as well. How would I have a menu, like the grub option, for accessing individual UEFI modes of the images?
