Tell me, what is “libre” for you, from what you’ve wrote so far, i see that it’s just new buzzword for you and you don’t understand what it is, read what tianocore is, if you don’t want it, to each their own, but tell me, how do you install OS on your pc without booting form usb/cd/dvd and not writing entries in uboot at least, and did you even installed Linux even once before?
