Here's a tutorial for making a bootable High Sierra .DMG image file for Mac OSX on win 10. I recently worked on a MacBook Pro Retina 15" A1398. It had the folder with the "?" in it and would not boot into MacOS. Using this method I was able to successfully install MacOS.

Originally I planned to make a second video to this, but realized the steps to actually boot from the USB drive are super simple, (granted the USB drive is recognized by the mac and DMG file worked).

Turn on the mac and wait until you hear the chime. Then press and hold the "OPTION" key until you see the boot menu pop up and it will list your drives. Then select the USB drive.
