    Dual boot puzzle


    I've just set up an old HP 6910p lappie with Windows XP (to support a parallel port EPROM programmer) and W10 in dual boot configuration.

    The BCD is set up to boot W10 by default with a ten second timeout to allow selection of XP or W10 safe mode.

    If I shutdown Windows 10, then next time I power the lappie on it boots straight to Windows 10 without offering the choince of what to boot! If I then do a restart it shuts down W10, and boots to the non-Metro selection screen so can choose which system to boot!

    That's not at all what I expected!

    I'm sure the answer is "obvious" but I don't get it, so if you can offer enlightenment I'll be delighted :)!

    In a Command Prompt (Admin) or Widows PowerShell with Admin run:
    powercfg -h off

    I can try that, but I use Hibernate regularly - is that just a debugging step?

    Unfortunately, that is likely the cause of your issue.

    Your thought to turn Hibernate off reminded me about "Hybrid Shutdown" aka "Fast Startup", so I did a "Shift Key/Shutdown" to do a full shutdown and that allowed the boot options screen to be displayed.

    I then went to the Power Options/"Choose what the power buttons do" and disabled Fast Startup.

    Shutdown w/o Shift Key, and rebooted and the boot options screen was again displayed.

    Thanks for the hint!
