E105

Xbox One fails to start with error E105 — a corrupted system update that typically needs an offline update or reset.

Possible hardware fault Last reviewed June 13, 2026

Explanation

What this error means

E105 occurs when you try to turn on the console and it can’t boot because the system software is corrupted or an update didn’t apply. It sits with the other startup errors; the repair path is the Offline System Update, then a reset that keeps your games if the update alone doesn’t fix it.

Diagnosis

Most likely causes

Cause How likely Fixable at home?
Corrupted system update Very likely Yes — offline update
Interrupted update or shutdown Likely Yes — offline update
Damaged OS partition on the drive Possible Sometimes — reset, keep games
Internal storage failing Possible No — Xbox Support

Repair

How to fix it

Ordered easiest-first. Try the next step only if the error comes back.

  1. Power-cycle the console

    Hold the Xbox button 10 seconds to fully power off, then restart and see if it boots.

  2. Boot the Startup Troubleshooter

    Power off, then hold Bind + Eject and press the Xbox button until you hear two beeps to open the troubleshooter.

  3. Offline System Update

    With the OSU file on a FAT32 USB drive ($SystemUpdate folder), choose “Offline system update” in the troubleshooter to reinstall the system files.

  4. Reset this Xbox (keep games & apps)

    If the update won’t apply, reinstall the OS while keeping installed games via the keep-games reset.

    ⚠ Use “Keep games & apps”. “Remove everything” wipes local saves not synced to the cloud — only choose it deliberately.

Escalation

When it's not your fault

Signs the problem is on Microsoft's side — or in the hardware — rather than anything you can change:

  • The console lost power or was unplugged during an update.
  • It started right after a system update rollout.
  • It was healthy until the failed boot.
When to contact Microsoft: If neither the offline update nor a keep-games reset clears E105, the internal drive is the likely culprit — contact Xbox Support. Check the official Xbox One server status page first, then reach Microsoft support if the error persists.

Questions

FAQ

What’s the quickest fix for E105?

The Offline System Update from a FAT32 USB drive. It reinstalls the system files that the failed update left incomplete, usually restoring boot.

Could this be the hard drive?

It can be if the offline update and reset both fail. Recurrent startup errors after clean repairs point at the storage hardware.

Do I lose my data?

Not from the offline update or keep-games reset. Cloud saves always return; only “Remove everything” risks local-only saves.
