There are three possible causes:
- Windows boot corruption – Windows startup files may be damaged.
- SSD or storage detection problem – the internal SSD may not be accessible or may have failed.
- UEFI boot configuration problem – the device may not be finding the Windows Boot Manager correctly.
Enter Surface UEFI.
Look for Boot configuration in the left-hand menu.
Check whether these options are enabled:
- Windows Boot Manager
- Internal Storage
- USB Storage
If Windows Boot Manager and Internal Storage are disabled, enable them.
Select Exit and restart.
If the device still doesn't boot, you can use a Surface Recovery Image.
You will need:
- Another working Windows PC.
- A USB drive (at least 16 GB).
- The exact Surface model and serial number.
Download the appropriate recovery image from Microsoft's official page:

If Windows Boot Manager is missing, or Internal Storage is unavailable, the problem may be with the SSD or its connection. If recovery USB also fails, hardware inspection may be necessary.
