I installed ubuntu 13.xxxx the latest version for desktop. I did so as a dual boot with uefi and secureboot enabled. Now I can boot into ubuntu just fine. However, I can't boot to windows 8. I have been told boot-repair is the answer to this. That's great. However, I can't boot to disc or usb at the moment. I can't turn secure boot off from the bios. So how would I go about running boot repair like this?
