Disable Secure Boot

[AS85]

In system utility, it will not allow me to highlight the disable field. It skips down to 1. Windows Boot Manager

And do I need to disable it if I am installing Win7 OEM on a new SSD (not on the current HDD with Win8 on it)?

Secure boot is used in association with Win 8 to prevent the likes of root kit invasions. As you are installing 7 this will not be effective, so I imagine it will simply be ignored. Meanwhile perhaps switching back to Legacy will remove the Secure boot? If you do that check your HDD priorities and boot order before you attempt to install as it will likely restore defaults.
(Secure boot also prevents 'Unauthorised' installations, surely Win7 doesn't fall in that category!)

You are correct - you have to select "Legacy Boot" and then restart to apply the changes. It then fails to boot upon restart and going back into the setup utility shows Secure Boot as "Disabled."
