After forcing a hard reset after my laptop hung up for a long time without any display it started trying to repair itself, unsuccessfully. It now permanently hangs up with the following message:
Your PC/Device needs to be repaired
The Operating system couldn't be loaded because the digital signature of a file couldn't be verified.
Error Code: 0xc0000428
You'll need to use recovery tools. If you don't have any installation media (like a disc or USB device). Contact your PC Administrator or PC/Device Manufacturer
Windows 10 is on the system, but I am unable to boot. It hangs up with the message that I transcribed and I can't get any further.
After you created the bootable windows 10 installation media:
1. Insert the flash drive into a USB port of the computer that needs to be fix.
2. Power the computer off.
3. Power the computer on, quickly start tapping the F12 key continuously until you see Preparing one time boot menu in the top right corner of the screen. At the boot menu, select the flash drive(windows 10 installation media) under UEFI BOOT.
4.In the windows setup, select your keyboard language.
You are facing the issue as some the drivers do not have proper signatures.

d. Click “Restart” button to restart your computer again.
e. This restart will bring you to the traditional menu list that has options such as Safe Mode, Disable driver signature enforcement etc.
