I have already written about disabling secure boot in Windows 8.1 when I was using a Dell laptop. A number of people mentioned in comments that for them the option to disable secure boot was greyed out in UEFI settings. They simply could not disable the secure boot for the reason that the option was available to them.
I did not face this issue until I bought this new Acer R13 ultrabook. It comes with Windows 8.1 pre-installed and of course it has UEFI instead of the legacy BIOS system. In order to dual boot Windows 8.1 with dual boot, I wanted to disable UEFI secure boot first. And when I checked in to UEFI settings under Security tab, I found that the option to disable secure boot was grey. Moving the arrow key up and down to select this option was futile.
In this article, we shall see how can we disable UEFI secure boot for Acer laptops (and perhaps systems from other manufacturers).
