Secure boot failed operating system is invalid

After trying to relocation Win8 through Ubuntu 13.04, and also completing the installation of the new OS, the following message appears once trying to boot:

"Secure Boot Failed Operating device is invalid."

I have tried installing Ubuntu 12.04 and Fedora 18 with equivalent difficulties (absent OS).

You watching: Secure boot failed operating system is invalid

I deserve to boot from the flash drives and run the OS without installing.

I have actually tried both automatic and also hand-operated partitioning via the exact same result.

You should go into BIOS and also disable secure boot.

It can be as simple as accessing the protection area in your BIOS and also finding a setup labeled secure boot and turning it off. If that's not the wording, disable UEFI booting.
