I had Windows 8 installed on my Asus X5551M, then I installed Ubuntu 14.04 over it. Now I want to go back to Windows 8 to sell the computer.
I created a Windows 8 USB using the exe from the Windows site and used that USB in the laptop. But when I try to override I get a red box with "Secure Boot Violation" Invalid signature detected. Check Boot Policy in Setup.
When I turn off Secure Boot, it just goes straight to Ubuntu. Any idea why this is happening?
