Question

A technician is trying to repair a computer that was infected with an encrypting virus. After disconnecting the system from the network, the technician images the computer. Upon startup, the system consistently presents a blue screen at the Windows logo. Which of the following should the technician perform NEXT to resolve the issue?

Options

  • APerform a BIOS'UEFI update
  • BExecute a clean install of the OS
  • CCheck the boot mode of the computer
  • DApply a different workstation image

Why each option

A consistent BSOD at the Windows logo after reimaging an infected system can indicate a firmware-level incompatibility that a BIOS/UEFI update can resolve.

APerform a BIOS'UEFI updateCorrect

A BSOD that occurs specifically at the Windows splash screen indicates the OS has begun loading but encounters a critical hardware-level failure before completing initialization. Outdated BIOS/UEFI firmware can be incompatible with the hardware abstraction layer expected by the imaged OS, and updating the firmware provides the correct low-level hardware support needed for Windows to load past that point.

BExecute a clean install of the OS

A clean OS install is a more drastic and time-consuming step that discards the image and should not be attempted before exploring less destructive firmware-level fixes.

CCheck the boot mode of the computer

Checking the boot mode addresses UEFI vs. Legacy mismatches, which is relevant but represents a configuration check rather than a corrective action at the firmware version level.

DApply a different workstation image

Applying a different workstation image does not resolve an underlying firmware compatibility problem and would likely reproduce the same BSOD on the same hardware.
