I am having trouble installing Kali in EFI mode. I want Kali to dual boot with windows 8.1 and Ubuntu 13.10 on my new Lenovo Yoga Pro 2, I can only install from USB, but I can not make my USB Efi bootable.

Any tips or sugestions on how to do this?

I hope to get some help for this soon... I've been struggling with it for the past 2 days.

Thanks in advance!
