Hey folks,
This is something I've experienced a few times. Here's what I've found works (note: make sure to remove anything plugged in to the tablet, excluding the power supply, before following this process):
Part 1 - Two-button shutdown process
Step 1 - Turn off the Surface; hold the power button for at least 10sec to ensure full shutdown
Step 2 - Wait at least 10sec
Step 3 - Hold the Volume Up & Power buttons for roughly
15sec (note: the Surface will go through something of a reboot cycle; do
not release the buttons until after at least 15sec)
Wait until the Surface boots up. It should load Windows this time. If so, proceed to Part 2
Part 2 - Fixing the American Trends Issue
Step 1 - (Assuming you've logged in to Windows), Swipe in from the right & choose Settings >
Change PC Settings
Step 2 - Select Update & Recovery > Recovery
Step 3 - Advanced Settings is where you'll find what you need to fix the issue. You may need to hit the "Restart" button if that's the only option available to you
Step 4 - Once you hit "Restart" you should be brought to a blue screen that says "Choose an Option". Select
Troubleshoot
Step 5 - Select UEFI Firmware Settings (you will need to hit "Restart" again)
Step 6 - Once you're back at everybody's favourite black screen, adjust the options thusly:
- Trusted Platform Module (TPM) & Secure Boot Control are both ENABLED
- Delete all secure boot keys > Yes
- Install all secure boot keys > Yes
- Exit Setup > Yes
(note: do not expect Step 6 to work if you haven't gone through the entire process as listed above. Simply executing Step 6 without the two-button shutdown & accessing the blue Advanced Settings screen from within Windows is not likely to solve
the problem)
When the Surface reboots this time, the logo screen should be normal (not that scary red looking boot screen). You may or may not also be taken to the American Trends screen again. If so, repeat Part 1. The Surface screen should be black, and Windows should
load.
This worked for me "permanently" the first time. However, after Refreshing/Restoring, it's likely to happen again, as your tablet is reverted to a previous point in time, before 8.1 and/or important updates.
Let me know if this helps! Would love to see if it works for all.
