Start-up problems MacBook Pro

Hello, my macbook pro shows only grey screen when I start it up. Before it would show a circle and diagonal. What to do? When I do command + R and turning it on, nothing happens. It just got it, it is a refurbished Mac.

MacBook Pro 13″, OS X 10.10

  1. Press and hold the power button on your Mac for up to 10 seconds, until your Mac turns off.
  2. Turn on your Mac and immediately press and hold both Command (⌘) and R to start up from macOS Recovery. 
  3. While in macOS Recovery, use Disk Utility to repair your startup disk.
  4. If Disk Utility found no errors or repaired all errors, reinstall macOS.
