Apple Event: May 7th at 7 am PT
Recently failed to update Mac to High Sierra. After some time couldn't even boot into Recovery Mode. When switched on only a huge power sign with tons of languages in front of it. After a few tries booting into Recovery it just showed up a symbol of a cross. What's happening to it and how can I fix it?

About the screens your Mac displays as it starts up - Apple Support
"A circle with a line or slash through it means that the selected startup disk contains a Mac operating system, but it's not a macOS that your Mac can use. You should reinstall macOS on that disk."
