How to delete the watermark that is not properly configured by Desktop Secure Boot in Win8.1

When using the Win8 system, UEFI was used to boot the computer, and the secure boot was turned off. After upgrading Win8.1 and activating the watermark in the lower right corner of the desktop, the secure boot is not properly configured. Restart and boot the secure boot and find that it can't enter the system. I don't know how to solve this problem.

Solution

1. Enter the BIOS and find the secure boot mode. Enter the custom option and you can select the following options.

2, return key msnagement, find install all factory default keys Enter, select YES and then enter, the following right side has become installed on the line.

3, retreat to the upper interface, change the secure boot mode back to standard save and exit, restart the computer, start the desktop watermark removal.

Delete the watermark in the lower right corner of the Win8.1 desktop that is not properly configured. I feel that the desktop looks much more comfortable. Although this operation requires changing the BIOS settings, there are not many steps, I believe everyone can do it.
