This is not Windows option but UEFI BIOS feature. Disable Secure Boot in BIOS and you get the same freedom as you get with disabling UAC.
only trouble is - if you don't do it, and windows does not start anymore, you're in a bit of a fix
Turning SecureBoot off won't cause Windows from not booting anymore. It just allows you to boot from more media.
i never said it caused windows not to boot - only IF
But what would that have to do with secureboot?
i warned that - IF secure booit is not disabled, you may have trouble starting from other devices (cd) - when windows does not start
that's all
that's all

Thanks for your comments, I was interested in the subject after installing a replacement system dis in a friend's laptop.
I replaced a 750 GB windows 8.1 system mechanical disk with an SSD by taking a disk backup with Acronis 2014 and restoring to the SSD.
The restored SSD system would not boot with UEFI configured in the BIOS although the original system booted with UEFI configured in the BIOS, to get the SSD system to boot I had to select Legacy boot as opposed to UEFI boot in the BIOS settings.
In order to restore the system to the SSD I used the Acronis 2014 bootable media which would not boot with UEFI configured in the BIOS.

Bad for Acronis. Looks like you did not copy entire drive.
without screenshots of what you did, we can't possibly say what was wrong - if any - only guess

You're correct noxcho. I only copied the system partition. Originally I planned to clone the disk but as the SSD drive was only 250 GB and the mechanical drive was 750GB (although only 93 GB was in use), I couldn't shring the system partition of the drive. I had re-located the swap file and removed hiberfil.sys but could still not shrink the system partition enough.
It isn't perceived as a problem that the SSD system now boots with non-UEFI configured in the BIOS.

That's why I said - bad for Acronis. Migrate OS for SSD from Paragon would copy the EFI partition and system partition together.
