How to see what the OS is doing during boot? (m4800)

I need to figure out how to turn on verbose mode I believe during boot. I am hacking my Dell Precision m4800 and it installs and restarts a few times. (Each time I have to manually boot using the usb installer I made.) But when it gets to what should be the last restart based off of my experience with installing Mojave on my actual Macbook it stalls or freezes with a sliver of the progress bar left (or that is what I am assuming, I let it sit for 30mins or som and the HDD light stopped flickering even.). I am following instructions from OSXLatitude.

If anyone has any tips on hacking a m4800 your input would be greatly appreciated.
