Can't edit boot commands in VMware for Android x86

I'm attempting to install Android x86 from https://www.fosshub.com/Android-x86.html following the steps on https://hackmd.io/@StanS/Android-x86 , and after getting to the point where I can reboot and boot into the OS, I go to edit the boot command for step 4. I hit e twice, but then I can't change the boot command. It just gives me a line with out the string that I need to edit. on the previous page, it has the string listed, but everything I search for just says it should be there.
