Windows 10: Boot manager loop after windows update

When I updated windows, it left me on a blank screen for over an hour so I turned it off, after that it wouldn't boot, after trying a tutorial online involving the command prompt, it keeps loading into the boot menu and doesn't let me off it, when I try and pick an option it goes black for a second and then loads back to boot menu, any help?

Windows boot manager

There could be some system conflict triggered after the said changes. To help you with your concern, we suggest that you perform a clean boot. A
clean boot is performed to start Windows by using a minimal set of drivers and startup programs. This will help to determine what is causing the issue on the Windows boot manager. To do this, click on this
link and scroll down to the
How to determine what is causing the problem by performing a clean boot section then follow the steps listed..

Note: If the installation is successful and the issue has been resolved. Please go through the section “How to reset the computer to start as usual” to reset your computer to the normal startup.

Boot loop

Hi Terri,

This issue occurs when there are broken components on the boot configuration data of your system. To troubleshoot your boot loop issue, we suggest that you boot in
safe mode through the Windows
Recovery Environment option. To do this, follow these steps:

• Turn on your computer. When the Windows logo appears, unplug and replug the device. Perform these steps three times.
• On the fourth instance, turn on your device without unplugging it. The Windows Recovery Environment window will appear.
  
• On the Choose an option screen, click Troubleshoot.
• Click Advance options.
• Click Startup Settings.
• Click Restart.
• Once your computer restarts, you will see a list of options. Press the F4 key to start your computer in
  safe mode.
  

Once done, we suggest that you perform a system restore after booting in safe mode. System Restore will be able to revert your PC or laptop to their previous state, which can be used to repair and recover system malfunctions or issues. Restoring won’t affect
your personal files, but it will remove apps, drivers, and updates installed after the restore point was made. To do this, follow the steps below:

1. Right-click the Start button, and then select
Control Panel.

2. Search Control Panel for
Recovery.

3. Select Recovery > Open
System Restore > Next.

4. Choose the restore point related to the problematic
app, driver, or update, and then select
Next > Finish.
