I have an Acer Aspire that I updated from Windows 8.1 to Windows 10 late last year. I moved and when I plugged in the computer, I now get a blue screen that states:
Your PC/Device needs to be repaired.
The digital signature for this 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.
Press Esc for UEFI Firmware Settings"
I have looked through a ton of threads and have not found one that addresses the fact that I cannot get to any menu to try and reboot in Safe Mode.
I can access the UEFI Firmware Settings menu, but it doesn't allow me to get any farther.
I have downloaded a Windows 10 ISO onto a USB device, but I cannot get the computer to boot from that location.
I cannot get to a Command Prompt either. I have nothing plugged into the computer, other than mouse and keyboard.
