I've been trying to dual boot Acer aspire 3 with windows 7 because it's working very slow with Windows 10. I made a UEFI bootable pen drive of 64-bit windows 7, But when I boot into the Pendrive `Security Boot Failed` message shows up.
I've disabled the secure boot but still, it's showing the same message.
could you please help me with this..?
