Troubleshooting

Windows 10 Build 15035 Media Builder

• Symptom: Surface RT or Surface 2 will boot the local Windows installation or boot loop if no local installation is found instead of booting from installation USB created using the Windows Setup or Windows Recovery Environment installation options. Fix: This issue is most commonly caused by not removing the Golden Keys / Longhorn jailbreak before attempting installation, for users of Surface 2 this may also be caused by not disabling Secure Boot using Yahallo. See the Tegra Jailbreak USB page for information on jailbreaking the device or alternatively recreate the installation USB using the Modified Windows RT 8.1 Recovery Environment option.

Common

• Symptom: Errors occur during modification of the installation image which indicate that removal of Windows Defender components from the image has failed or Windows Defender is still present after installation despite it being selected for removal. Fix: Temporarily disable Windows Defender Tamper Protection on the host system and rebuild.

• Symptom: Device will hang on the UEFI boot logo when attempting to boot from the installation USB and will remain hung until powered off with no error output provided. Fix: Make sure you are using Windows Media Builder v2.4f or above, if the issue still remains the only advice is to try building the installation media on another PC and perhaps use another USB drive.
