How do I disable UEFI?

I am simply trying to boot from a USB or the disc drive in an Aspire E1-510p-2671.

 

I have set the boot priorities correctly.

I have turned SecureBoot off.

I have turned on the F12 boot menu.

 

If I turn the machine on and let it do its own thing, it loads Windows 8.

If I tape F12 to go to the boot menu so I can manually select something, my only options are Windows Boot Manager, or, if I have network boot enabled, I get two network boot options.

 

I cannot change SATA mode off of AHCI, and I cannot change boot mode off of UEFI. I have scoured Google for this issue and it seems loads of people with Acer laptops cannot boot from anything other than their HDD. Changing the UEFI option has fixed it for everyone I have seen able to switch it, but I cannot switch it. What is going on? Why am I being blocked from booting from particular devices/ports? Makes no sense.
