I am running Mojave on my macbook pro and previously had bootcamp installed. I removed it, but there was some information left behind. Prior to posting here, I found a website that had me go into terminal terminal and find a parition called EFI, I went through some steps to try to remove it, but on the final step, it asked me to go to cd /Volumes/EFI/EFI however terminal said it could not be found. When I rebooted my computer, I no longer got the microsoft error page, but it was a black screen. I now have to restart holding the option key and it shows two drive, EFI Boot and my normal one. I can't figure out how to remove this EFI Boot. Any help would be appreciated. When I type diskutil list, I currently see Type EFI Name EFI identified disk0s1
