Abstract
A method for allowing a computer to boot from a user trusted device is provided. The computer includes a long-term data storage device storing operating system (OS) services. The user trusted device is connectable to the computer and stores a boot loader detectable and executable by a firmware of the computer, an OS loader designed to load an OS of the computer, and one or more crypto drivers designed for allowing access to the OS and data stored encrypted on the data storage device. The method comprises letting the boot loader be executed to cause to transfer the OS loader from the user trusted device to the computer and executing the transferred OS loader to cause to execute the one or more crypto drivers for the OS and the data stored encrypted on the data storage device to start the OS services and complete booting of the computer.
