I have a HP Pavilion 15-e056sl Notebook PC with Microsoft Windows 8 preinstalled, now in dual-boot with Arch GNU/Linux. Actually I turned off SecureBoot from BIOS in order to use GNU GRUB at startup (if SecureBoot is activated GRUB is not recognized).
So, for me, SecureBoot now is correctly configured (=off).
Accordingly, how I can remove that misleading message?
Before upgrading the system to Windows 8.1 I was really proud of my dual-boot-machine and everything worked fine. Now I have that horrible warning message on the right corner of my desktop. But it is really a misleading message!
