Firmware errors
17 errors. Choose the message that matches your computer.
BIOS-BOOT-LOOP
The PC restarts in an endless loop after POST. Problem with UEFI boot records or corrupted BCD.
FirmwareUEFI-SHELL-ERROR
The system booted into the UEFI shell instead of the OS. The boot record is missing or corrupted.
FirmwareFIRMWARE-ROLLBACK-BLOCKED
An attempt to downgrade the BIOS was blocked by board protection or Intel Boot Guard. The steps below are ordered to resolve this efficiently.
FirmwareNVRAM-FULL
UEFI NVRAM is full of variables. It causes boot problems and the inability to save settings.
FirmwareCSM-CONFLICT
Compatibility Support Module (CSM) conflicts with UEFI OS or Secure Boot. It's also often linked to old OS installed in Legacy mode.
FirmwareUEFI-BOOT-LOOP
Every time the PC is started, the system automatically redirects to the BIOS instead of Windows. It's also often linked to change SATA mode (AHCI/RAID).
FirmwareCSM-CONFLICT-VGA
The CSM module has been disabled, but the older graphics card does not have UEFI GOP (Graphics Output Protocol). It sometimes comes down to outdated firmware on GPU.
FirmwareSEC-BOOT-VIOLATION
System boot stopped due to unsigned bootloader or driver. This usually traces back to installing Linux (Grub) or modified Windows and unofficial drivers on.
FirmwareNVRAM-FULL-ERR
The NVRAM memory capacity for storing boot variables is full. It's most often caused by too many OS installed and UEFI error (eg creating duplicate entries).
FirmwareUEFI-SHELL-FALLBACK
It started the EFI command interface instead of the operating system. It's most often caused by deleted EFI partition and disk not found by BIOS.
FirmwareME-FW-UPDATE-FAIL
The Intel Management Engine firmware update failed or was interrupted. This can also stem from power interruption while flashing.
FirmwareAMD-AGESA-MICROCODE
The installed processor is not fully supported by the current version of AGESA libraries in the BIOS. Follow the steps below to fix it.
FirmwareACPI-TABLE-CORRUPT
Windows BSOD ACPI_BIOS_ERROR due to faulty BIOS power management configuration. Follow the steps below to fix it.
FirmwareFAST-BOOT-HANG
The computer won't start because it's stuck in the fast boot phase. This can also stem from incompatible USB device connected.
FirmwareBIOS-PWD-LOCKOUT
Access to the computer is blocked due to an unknown UEFI administrator password. The steps below are ordered to resolve this efficiently.
FirmwareSSD-FIRMWARE-BRICK
An SSD firmware update failed or was interrupted, leaving the drive in an unbootable 'bricked' state. The drive may no longer be recognized by the system, appear as 0 bytes, or fail to initialize.
FirmwareINTEL-ME-FIRMWARE-ERROR
The Intel Management Engine (ME) — a separate microcontroller embedded in Intel chipsets — has reported a firmware error. The ME handles out-of-band management, AMT (Active Management Technology), and hardware…
