I have a z580 Ideapad that I've had for quite some time(2 - 3 years). I can access the boot menu through the novo button perfectly fine, when I select my USB drive with my OSX bootable image on it, it loads to the lenovo screen, then reloads and loads up windows 8. I have changed the settings in the BIOS to allow the USB to boot first in the boot order, however this doesn't change anything.
Here are some images of my BIOS:
I have heard people with similar problems to mine, have disabled the secure boot setting but it doesn't appear in my BIOS for some reason.
Also sometimes, my USB drive doesn't display properly in the BIOS boot order list, or on the boot menu. In the picture above that's what it shows when it doesn't appear in the boot menu, but when it does, its called USB HDD: Generic Flash Disk.
Its not a problem with USB 3.0 ports as I have tested all ports on my computer (2x 3.0, 2x 2.0).
Any help is greatly appreciated.

For Windows 8 to boot from a USB requires some tricks (at times) -
1) Make sure Secure boot if OFF (I know you said its not available, but I have to mention this)
2) Keep Boot mode as Legacy. (I suspect this is what you are missing)
3) Enable Boot from USB.
Save the settings and restart with the USB plugged in.
If it still doesnt boot, try to re-create the bootable USB.
