If you're unable to enter the Windows Recovery Environment, you can use another computer to create a bootable USB drive containing the Windows installation. This USB can then be used to run repair tools on your affected computer.
You can create using the media creation tool, download it on this link(Create a USB device with an installation image): https://www.microsoft.com/software-download/win...
Go to BIOS/UEFI and change to boot from the USB device.
On the installation screen click on "Repair your PC" in the left bottom.
Click on Troubleshoot > Advanced Options > try the available options. Thank you.
