This is the second furtherest I’ve gotten to installing. The first time I was able to boot to the disk partition menu before installing

I have a Lenovo thinkpad t440s. I5-4300U, 500GB HDD, 12 GB RAM & Intel HD Graphics.

I followed two different guides that did not work for me. I tried dortania’s opencore install guide and a guide on YouTube by valnoxy. I’m really at a loss for words and I’d be very grateful if someone can point me in the correct direction.
