Good day!

When starting the computer, all you get is a black screen.
Here's the solution:
Turn on your computer and tap the "F8" key to get "Windows Advanced Options"
( if boot menu appears, please press "Esc" key and keep tapping on the F8 key) .Select "Safe Mode". Go to Control Panel -> Backup and Restore > Recover system settings or your computer > Open System Restore > follow the wizard to restore the system to the state before the issue occurred.

Otherwise,

Open the BIOS > Load default settings > Make sure that your hard drive is detected in the BIOS. Set your hard drive (where OS is installed) as primary boot device. Save the settings and exit from the BIOS.
