My Laptop was showing folder sign with question mark when try to login. So I tried to reinstall the mac at the last moment it showing error message that it could not install and restart the program. And when I check with utility disk it's showing error 'exit with error code 8'

If your Mac starts up to a question mark

If your Mac doesn't start up all the way - Apple Support
