Inspiron 5749 error on startup because the digital signature on a file could not be verified
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:
Recovery
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.
File: \WINDOWS\System32\intelpep.sys
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.

I'd suggest using another computer and create a windows 10 installation media from the link below. You'll need a blank USB flash drive with at least 8GB of space.
Download Windows 10 - microsoft.com

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.

After selecting the Repair Your Computer option, click Troubleshoot, and then Advanced Options. You could either run System Restore, Startup Repair or Run System File Checker into Command Prompt.

You are facing the issue as some the drivers do not have proper signatures.
Use an installation media and follow these steps to disable driver signature enforcement and check.
a. In the ‘Windows setup’ page select the ‘language to install’, ‘Time and currency format’ and the ‘keyboard or input method’ and click on ‘next’.
b. Click on Repair your computer.
c. Click on Troubleshoot and then select Windows Startup Settings.
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.
You can create an installation media by referring to the following link.
