Hi,

I just want to allow my dell laptop 5500 latitude (2018) to boot from any device, especially from a SSD drive with USB 3 connection where there is a Ubuntu.

So I want to change all the UEFI bios that prevent me to do that, and at the same time avoid to lock my windows 10 main OS which is encripted with bitlocker.

Can you help me? I don’t have almost any idea where to start...
