The user partition includes: a user partition address range; a host-selected operating system; and a host-selected master boot record. The host-inaccessible hidden partition includes: a hidden partition address range outside the user partition address range; diagnostic software for determining a condition of the computer system; and a drive-selected master boot record for waiting for a user input; if the user input is received within a predetermined time period: loading and executing the diagnostic software; and if the user input is not received within the predetermined time period: loading the host-selected master boot record; and loading and executing the host-selected operating system identified by the host-selected master boot record.
