Two ways :
1) You simply turn off secure boot and it'll boot your unsigned binary. If your 
machine doesn't have that then it's a bug and you should complain to the 
retailer - and return the machine (which by now is not in a re-sellable 
condition) as not fit for purpose (you did mention the need to boot unsigned 
binaries when buying it didn't you ?) AIUI, part of MS's specs for 
manufacturers is that they allow secure boot to be disabled - precisely to head 
off the "this machine can only run Windows, monopoly abuse, ..." arguments.

2) You create your own key, install that in the system, and sign your binary 
with that key. This means that the machine will still boot Windows 8+ which 
won't otherwise boot.
Again, if the machine won't allow the installation of your own key then that's 
a bug - it's (AIUI) part of the UEFI spec to allow keys to be added.

[U]EFI in itself isn't all that bad - what some manufacturers do with it, and 
the hash they make of it, is often bad.
