I am currently stuck in a never-ending boot sequence in Windows 10 after failing to properly shutdown due to a misbehaving USB thumb drive. How can I escape? This is how it came about:

Before hardware-disconnecting a USB thumb drive, I normally try to be on the safe side by both

1. software-ejecting the drive via the taskbar and then
2. clicking on remove device in Control Panel\Hardware and Sound\Devices and Printers.

This usually works just fine. This time, however, I was in a rush and forgot step 1, so when I executed step 2, my Windows 10 froze up (probably a quirk in my system, because this probably isn't expected behaviour).

Since the OS was hardly reacting anymore, the only solution I saw was to force-quit Windows via shutdown.exe /s /f /t 0. However, Windows 10 didn't properly shut down, but kept stuck with a blue screen saying "Please wait for the System Event Notification Service" below an endlessly rotating wheel:

I waited for 30 minutes, but since no keyboard inputs had any effect and CTRL+ALT+DEL didn't bring up the task manager screen, I didn't see any other remaining choice aside from pressing the ON/OFF button on my computer. When I subsequently pressed ON/OFF again to restart the computer, to my great surprise the same blue screen with "Please wait for System Event Notification Service" reappeared instead of the normal boot sequence.

Retrospectively I understand why that happened: My ON/OFF power button was not configured to shut down the computer but to enter hibernation. In addition to that, this setting may be irrelevant, because apparently by default Windows 10 hibernates instead of truly shutting down anyway:

By default, Windows 10 enables a feature called Fast Startup (HybridShutdown) that can shut down and boot up your PC much faster thanWindows 7 or previous versions of Windows. When you shutdown Windows10, you’re actually performing a partial hibernation.

If you prefer to have your PC completely shut down, you can eitherturn off Fast Startup feature or use the following methods to fullyshutdown Windows 10.

When I turn the PC off and on again via ON/OFF I always boot into said blue screen, so I am currently stuck in an endless shutdown/boot sequence.

I even disconnected the power cord from the PC to make sure it is really OFF (or hibernating as it turned out!) and not just sleeping.

Before Windows 10 I previously worked on Windows XP which allowed to interrupt the normal boot sequence by pressing F8 to enter the advanced boot menu and/or to discard hibernation state and boot normally ("delete restoration data and proceed to system boot menu"):

This is exactly what I'd need now, because Windows 10 keeps trying to resume my hibernation state which is currently stuck in shutdown. So I need to tell Windows 10: "Please don't try to resume the hibernation state, because it will never work, but restart fresh instead."

So the question is: How can I discard the hibernation state and boot normally in Windows 10 ?

Of course I would potentially lose any unsaved work this way (not applicable in my case though because I didn't have any unsaved work prior to the freeze-up), but this is still better than any more ungraceful methods which risk data corruption on the system drive.

I tried pressing all F-keys upon start-up but none of the function keys brought up an advanced boot menu (like F8 in Windows XP).

So how can I access the advanced boot menu in Windows 10 ?

All methods I found on the Internet required access to the OS (e.g. telling Windows to enter advanced boot menu on subsequent restart), but this doesn't work for me since the boot sequence fails and I cannot enter Windows.

Update:

Since I failed to find a solution, I pressed the ON/OFF key again as soon as the Windows logo appeared, as the suggested solution on some Internet sites. The unexpected effect was an ungraceful immediate shutdown (with the risk of data corruption on the system drive) – which I had tried very hard to avoid.

Due to this accident, I am now out of the endless emerging-from-hibernation-into-failed-shutdown loop.

But I would like to be prepared for the next time I end up in such an endless loop.

So how can I enter the advanced boot menu during the Windows 10 start-up sequence in order to discard the hibernation state ?

All resources I found on the Internet suggest force-crashing(!) the Windows startup 3(!) times by interrupting the power supply. This is batshit crazy!!! I can't fathom that the only way to access the advanced boot menu during Windows 10 start-up is something highly prone to data corruption. There must be another way, right?
