    Hi guys, I would like to know more about the Windows recovery on x86/64 systems equipped with UEFI firmware, in particular I would like to know if there is a way to trigger the Recovery screen (the Metro style one "Advanced startup") without going to "Settings/Update&Security/Recovery/Advanced startup".
    Also, is this "system" embedded in a EFI binary or the bootmgfw.efi (or bootx64.efi) bootstraps it from elsewhere?

    Are there some gurus/experts around here that can answer my question?

    Thank you very much
    Have a nice day :)

    Hold down Shift key while restarting
    That should trigger Advanced Startup

    From an Admin CMD Prompt you can also run "reagentc /boottore" then "shutdown -r -f -t 0".
     
    Stop hovering to collapse... Click to collapse... Hover to expand... Click to expand...

    Thank you, I didn't know about this trick :)
    However is there a similar method in case the system (Windows 10) won't be able to reach the desktop/login screen? Like Windows 7 with the F8 key

    I'm curious about this as well, but I think you may have to boot from a copy of windows 10 (DVD or USB) if you can't get to any GUI.

    yes, there is a comman line that you can run which will allow you to access recovery options at startup in case your normal session is not accessible anymore for some reason, that's very easy, all you have to do is going to command prompt (in admin mode) then type this :

    Code:
    bcdedit /set {default} bootmenupolicy legacy
    This way, you will be able to access recovery options simply by pressing F8 key quickly at startup

    If Windows fails to boot 3 times in a row it will automatically enter the recovery environment.
