    NOTE: Any user can do this option at boot.

    1.
    Boot to the Startup Options screen.

    2. Click on Change defaults or choose other options at the bottom. (see screenshot below)

    Note   Note
    This will let you see what the default OS is under the Windows Boot Manager section, and to see the description (name) and identifier of the operating system(s) listed in Windows Boot Manager under the Windows Boot Loader section(s). For example, Windows 7 Ultimate (description) as {08ea7340-743c-11e1-a16b-000c29ebef34} (identifier).

    3. In the elevated command prompt, type the command below for a listed OS that you want to be the default OS to start, and press Enter. (see screenshot below)

    Great tut Shawn. That is even easier than with EasyBCD. And very useful if you have Win7 and Windows 8 because then you can chose Win7 as default to avoid the act of the UEFI boot.

    Thank you Wolfgang. I also find that using the Advanced Startup shortcut or option (option two) while in Windows 8 makes it real easy to switch to say Windows 7 without the usual double full restarts.

    Hi Brink. Is there any way to do this, to another person's computer's hard disk? Like his dual boot is failing to boot up from Windows 8, and can I take out his hard disk, and edit his hard disk so that when it gets pop back in to his computer, it boots from Windows 7 instead?
