Sparkylinux 4.3 86-64 fails to boot from USB stick

[bill-p]

I've downloaded the latest SparkyLinux LXDE 86-64 image and DD'd into a USB stick. When I try to boot this, I get the error message,
presumably from the BIOS:

   The system found unauthorised changes on the firmware, operating system or UEFI drivers.
   Press [OK] to run the next boot device .....

I've checked the MD5 sum is OK. The machine will boot from a ubuntu-audio USB stick!

It's a new machine, ASUS Z170-K motherboard, with Intel i5 processor.

Any ideas?   :-\

You should disable security boot.

Thanks, I had no idea what UEFI was - just found a brief outline. I managed to find the right place in the huge list of BIOS pages and
found Boot Security. Changed it from 'Windows' to 'Other OS'! That seems to have fixed it!
