CONCEPT MODELS

See the lesson as a system

Use these visual guides to connect the key ideas before answering the questions.

Map the decisions in Diagnosing Boot ProblemsConnect power-on evidence, firmware and post, boot device selection, and windows boot stage without collapsing their evidence.
Map the decisions in Diagnosing Boot ProblemsA support map connects four subject-specific decisions used in diagnosing boot problems and shows the evidence produced by each decision.
Power-on evidenceEvidence for power-on evidence
Firmware and POSTHardware detection and firmware errors are known
Boot device selectionThe firmware points to the intended boot device
Windows boot stageEvidence for windows boot stage
Use Recovery and data safelyConnect recovery and data to its approved starting method, expected result, and safety boundary.
Use Recovery and data safelyA practical support model connects recovery and data with a method, result, and explicit safety boundary.
Recovery and dataFocus on recovery and data
Starting checkReview recovery option impact before selection
Expected resultOutcome for recovery and data
Safety boundaryReview recovery and data risks
