Ubuntu based systems like the Alienware X51 R2 and other Dell systems come with a function called "Secure Boot" enabled. Secure Boot allows only bootloaders signed with trusted key pairs to be booted on a system.
In accordance with the GPLv3, customers are required to be able to make modifications or replace the GRUB2 bootloader shipped with some Linux systems that have secure boot enabled. GRUB2 is an open source bootloader that has been signed using a private key.
Customers are welcome to either use their own public/private key pair for signing the bootloader or disable secure boot if they want to replace or modify the bootloader.
