I have tried to erase all data from my MacBook Pro and erase and re install osx disk
Short answer: no. Any Mac that supports Internet recovery could theoretically boot to Internet recovery even with the hard drive removed. Press and hold command-option-R immediately after powering on the mac. If it does not detect a physical network Internet connection, it will prompt you with a drop-down menu displaying a list of available wifi networks. Once joined, it will take a REALLY long time to boot, but eventually it will load a recovery OS. Here you can reformat your hard drive (or find out if one is installed), reset your password, access Safari and, of course, reinstall your OS.
