ATI 2013 Build 5551 Recovery CD NOT Recognized By HP Laptops

Thread needs solution

My new HP Pavilion g6-2237us Intel I3-3310M laptops don't recognize the iso-burned recovery cd. The error message says "EFI file failed to authenticate" when booting from the internal dvd drive. Any workarounds that allow a recovery cd boot before the new laptops are OS-booted for the first time?

You need to disable Secure Boot before booting from the Rescue Media.

You also need to enable legacy boot after you have disable the secure boot option. Do your recovery CD test/operation, then revert the settings to where they were in the BIOS.
