What This Code Means
This message indicates the firmware/bootloader detected a partition table state that prevents booting. It can occur after disk cloning, partition edits, drive corruption, or when boot mode (UEFI vs Legacy) does not match the disk format.
Where Users Usually See This Code
- After cloning a disk or changing partitions
- After an unexpected shutdown during disk writes
Why This Code Appears
- Partition table corruption
- Boot mode mismatch (UEFI/Legacy)
- Incorrect active/boot partition state (legacy systems)
What Typically Happens Next
- The machine cannot boot until disk structure is repaired
What This Code Is Not
- It is not an OS application crash
- It is not a CPU/GPU failure indicator
Troubleshooting Checklist
- □ Verify firmware boot mode matches the disk (GPT/MBR)
- □ Use official recovery media to run disk/boot repair tools
- □ Back up important data before partition repairs
Notes And Edge Cases
Modern UEFI systems rely on an EFI System Partition; deleting or misplacing it can break boot.
