Last ditch effort to restore your ASUS laptop to factory fresh configuration.
You can order ASUS Authorized Windows Notebook Recovery Media. Here's the link. It's not free but the service will restore your OS drive to OEM specs.
https://www.asus.com/us/support/article/782/You could also use your eSupport folder and the ASUS Installation Wizard to install all the ASUS programs and drivers for your laptop. It sounds like you lost your OS. I suggest you take some time to review the contents of the "Sticky" labeled "Make a copy of your eSupport Folder before formating your OS drive! " found at the top of the G Series Gaming Notebooks forum.
Good Luck
