5.003 - Booting into alternate operating systems is permitted.

Information

Allowing other operating systems to run on a secure system, can allow users to circumvent security. If more than one operating system is installed on a computer, each must be configured to be compliant with STIG guidance.
NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Configure the system to prevent running non-compliant alternate operating systems.
