If the device is stopping at the BitLocker recovery key screen and the recovery key is not available, the supported reset path is to use a Surface USB recovery drive to reinstall Windows.
Important: this process deletes all personal files, resets settings, and removes installed apps.
Steps:
- On another working Windows PC, download the correct factory recovery image for that Surface from the Surface Recovery Image Download page.
- Create a USB recovery drive for the Surface.
- On the Surface, make sure it is turned off and plugged in.
- Insert the USB recovery drive into the USB port.
- Press and hold the volume-down button, then press and release the power button.
- When the Microsoft or Surface logo appears, release the volume-down button.
- When prompted, select the language and keyboard layout.
- Select Recover from a drive or Troubleshoot > Recover from a drive.
- If prompted for a recovery key, select Skip this drive at the bottom of the screen.
- Choose:
- Just remove my files if the device will be kept
- Fully clean the drive if the device will be recycled or transferred; this is more secure but takes much longer
- Select Recover.
If the built-in Windows reset feature is failing, Microsoft recommends trying Windows Update first if possible, or using a Surface USB recovery drive instead.
If Windows still does not start after using the USB recovery drive, the next step is service or repair support.
