Try booting from the installation media
https://www.microsoft.com/en-us/software-download/techbench
Choose Windows 10, the first item in the first drop down (not single language at the bottom)
Next choose your language and your bit version (32 or 64 bit to match your system architecture or in the case of an upgrade, to match your currently installed version of Windows).
That will provide an ISO that will upgrade, repair (or clean install) either or both Windows 10 Pro and Home.
Once you have downloaded the ISO you can use ImgBurn to burn it to a DVD

OR
Rufus to burn it to a USB ThumbDrive

When you've managed to boot from the installation media you need to click the Repair Your PC link on the second page after the Choose a Language and Keyboard layout page.
That should get you to the Advanced Troubleshooting options, where you can try
Startup Repair
System Restore
OR
Maybe give Startup Settings Icon a try and see if you can boot into Safe Mode from there.
