I'm currently trying to install macOS Catalina on my Dell Latitude E6220 (specs below). I've followed dortanias guide, but I can't boot into the macOS setup. I select the USB from my BIOS, it shows the "Boot Menu", and after about 5 seconds, it says "Choose the operating system: timeout". I cannot interact with the menu at any point, I've tried the number keys, arrow keys, and basically every other key, but it won't do anything.
Specs: i7-2640m Intel HD 3000 10GB ddr3 1600mhz 128gb SanDisk SSD.
