To do that you have 2 ways:

2. Power on, than hold: option
3. Select your Recovery Partition holding: command + S
4. You will see a boot in a "console/terminal" mode.

6. run cmd: reboot

Using internet recovery

1. Power off your notebook.
2. Power on, than hold: command + shift + R
3. Select your Wi-Fi
4. Wait to download the recovery "image" from internet (progress bar with World/Internet logo).
5. When at end of download, hold: command + S
6. Keep holding "command + S" until boot start (progress bar with apple logo).
7. You will see a boot in a "console/terminal" mode.
