HP Notebook 17z-y000 updated Windows 10 and now will not boot up.

When my husband closed down his laptop last night, he was given the option to update (Windows 10) and shut down.  He did so, but it never shut down.  He turned it off, and this morning turned it back on but it won't boot.  We unplugged it and removed the battery for a minute, then replaced and plugged it back in, but it still won't boot.  Just shows the little circular dots.  Tried turning it off, then on then pressing escape to theoretically reach a prompt allowing us to press f2, but that didn't work either.  Can anyone assist?

The Microsoft Windows September Patch Updated just came out this last week and what are seeing onscreen is an indication of Windows Update failing to complete properly.

These problems were reported with KB4532693 back in February of 2020, and more recently, with KB4556799. Unfortunately, this is NOT a new issue with Win10 Windows Updates.

First thing you need to do is see if you can restart in Safe mode -- by doing these steps: https://www.tenforums.com/tutorials/2304-boot-into-safe-mode-windows-10-a.html

If you don't know how to start using Advanced Startup Options, then read this: https://www.tenforums.com/tutorials/2294-boot-advanced-startup-options-windows-10-a.html

Then, follow these steps to reset Windows Update: https://www.tenforums.com/tutorials/24742-reset-windows-update-windows-10-a.html

If these work, when you finally reboot, you should then be able to login to a working Windows desktop.
