After some trouble installing Elementary OS Juno I managed to complete the installation by modifying "quiet splash" into "nomodeset". Before that, it would crash and show an error message: "couldn't get UEFI db list". So now my first problem is the fact that every time I boot the computer I have to make this change into nomodeset. If not, as said, it shows the error message and goes black. Second problem is the wifi connection. There's only ethernet connection. Typing iwconfig in the terminal shows no device. It's a Realtek RTL8821CE 802.11ac. Computer is an HP 255 G7 Notebook. Thanks in advance!
