1. An information handling system comprising:
a central processing unit (CPU);
a random access memory (RAM) communicatively coupled to the CPU;
a communications port communicatively coupled to the CPU; and
a basic input/output system (BIOS) comprising boot firmware configured to be executed by the CPU when the information handling system is booted and/or powered on, and configured to initialize information handling resources of the information handling system and/or initialize interoperation of the information handling system with other information handling systems, the BIOS further configured to:
responsive to a failure to complete a phase of execution of the BIOS, create a virtual disk on the RAM such that the virtual disk is mountable as a volume by a second information handling system coupled to the information handling system via the communications port; and
store telemetry information to the virtual disk wherein the telemetry information includes a firmware image of the BIOS and one or more recovery error codes.
