I have a Dell XPS 8700 that failed Windows 10 anniversary update until UEFI secure boot was
turned off.
It apparently then completed but I cannot re-enable secure boot without the same boot problem advising

you'll need to use recovery tools.
Is there a solution to enable UEFI secure boot ?
I am using a Dell XPS 8700 pc with an SSD drive. The Windows 10 update was installing
then after one of the reboots the error above
The pc was running prior to the update and had UEFI OS , secure boot enabled, no prior problems.
I attempted to do any of the safe mode boots but none would proceed.
Disabling the UEFI safe/secure boot mode apparently let the install continue and the d
as it did before with I believe completion of the installation of Windows 10 anniversary update.
PC now shows Windows 10 home Ver 1607 ..
The problem returns if I enable UEFI secure boot and the PC stops. I would like to determine a way
to locate the problem or issue. related to the secure boot. Using the media creation tool may just
repeat the problem once secure boot is re-enabled.
Dell lists that they have tested XPS 8700 with this update and have not indicated problems no mention of secure boot issue.
