Step 3: Configure UEFI Boot Entry UEFI requires an EFI bootloader. Copy the 64-bit UEFI bootloader:

In the modern era of IT asset management and system recovery, three acronyms often collide in a single, high-stakes task: DLC , UEFI , and ISO . While "DLC" typically means "Downloadable Content" in gaming, within enterprise and systems engineering circles, it stands for Dell Lifecycle Controller (or more broadly, Driver Lifecycle Control). When you need to create a custom bootable image that supports UEFI and injects DLC payloads (like firmware, drivers, or OS deployment tools), you are entering complex territory. within enterprise and systems engineering circles
