Enabling DHCP Scope to Boot on UEFI for Imaging

Secure Boot Configuration helps a computer resist attacks and infection from malware. When your computer was manufactured, UEFI created a list of keys that identify trusted hardware, firmware, and operating system loader code. It also created a list of keys to identify known malware.
When Secure Boot is enabled, the computer blocks potential threats before they can attack or infect the computer. For example, Secure Boot can prevent your computer from starting from illegally copied CDs or DVDs that could harm the computer. Also it formats the Computer with GPT which is the way to move forward. Devices like surface pro support UEFI only.
