Using your sister's disks is called Pirating Software and it's a felony.

Answer 3

1-Put the first disk in

2-Reboot your MacBook while holding the C key

3-Choose your language

4-Follow the installation process...

****choose "Upgrade" or "Archive and install" if you don't want to loose your stuff...****
