   A Dell PowerEdge R650 server is in UEFI mode with Secure Boot enabled. The administrator installs a custom Linux distribution that uses a self-signed boot loader. After installation, the server fails to boot. The administrator confirms the boot loader is correctly installed on the GPT disk. What is the most likely cause and solution?

   • AThe UEFI boot manager is not detecting the boot entry; recreate the boot entry using efibootmgr.
   • BThe server must be switched to Legacy BIOS mode to boot the custom Linux distribution.
   • CThe GPT partition table is corrupted; recreate the partition table and reinstall the OS.
   • DSecure Boot is blocking the self-signed boot loader; disable Secure Boot or enroll the custom key.
