Hi,
Error 0x800f0922 and SAFE_OS / MIGRATE_DATA failures are usually related to system partition issues, driver conflicts, or something blocking the upgrade during the early boot phase.
Since you already tried DISM, SFC, and resetting update components, here are a few more things to check:
- System Reserved / EFI partition space
- Make sure it has enough free space (this error is often linked to low space there)
- Disconnect unnecessary devices
- Remove USB devices, external drives, etc. before updating
- Check for incompatible drivers
- Look at logs in:
C:\$WINDOWS.~BT\Sources\Panther\setuperr.log - MIGRATE_DATA failures are often caused by drivers or data conflicts
- Look at logs in:
- Disable security software completely
- Even after uninstalling, some remnants can interfere
- Try upgrading using ISO (in-place upgrade)
- This sometimes bypasses update-related issues
If the failure happens specifically during SAFE_OS phase, it usually means something is blocking the system during the upgrade boot stage (often drivers or disk-related issues).
Let me know if you find anything in the logs 👍
