Why each option
When creating a multiboot system, operating systems must be installed from oldest to newest because each newer Windows version includes a bootloader that can detect and register older OS installations.
Windows XP, Vista, and 7 must be installed in ascending version order because each OS writes its own bootloader during installation. Newer bootloaders (Vista and 7) are designed to detect and add older Windows installations to the boot menu. If a newer OS is installed first, its bootloader will be overwritten by the older OS installer, breaking the ability to boot the newer OS.
Installing Vista first, then Windows 7, then XP would cause Windows XP's installer to overwrite the Windows 7 bootloader, preventing Windows 7 and Vista from being selectable at boot.
Installing Windows 7 first, then Vista, then XP is reverse order and would result in the XP bootloader overwriting newer bootloaders, breaking the multiboot configuration.
Installing Windows 7, then XP, then Vista installs an older OS after a newer one, which overwrites the newer bootloader and corrupts the multiboot setup.
