2 - Create USB drive using isomorphic build 207 SELECTING UEFI - Check Point appliance option

3- Plug USB drive on Security Gateway, and reboot the Security Gateway or turn on

4 - Don't select any option here, JUST WAIT firewall recognize the USB drive and show the next screen

5 - Select option GAIA - UEFI installation - Serial to start format using USB Drive
OBS: If this option appears will work fine if you

6 - Wait firewall finish installation of the new iso. 
OBS: Before the Installing OS start will see a lot of lines starting processes.

7 - Optional - For me after finished installation of the new .iso for my specific 9000 model, was present this message error when I try import offline Recommended Jumbo Hotfix .tgz, but was the right JH, upgraded correctly for Recommended DA, and the .iso was right too for Security Gateway and don't For Maestro like some friends have difficults too understand this menssage. 
So I just connect the firewall on a Lab WAN link using basics configuration (Automatically IP, dafault static route) just for my firewall out to Internet, and was possible upgrade the Jumbo Hotfix using web CPUSE.
