I am a complete novice at this, but after looking for the answer to how I could start the GUI. I found out what worked for me. I had downloaded Tiny Core 7.1. Only one of the options worked. I downloaded Coreplus 7.1 and could not get any of them to work, until I checked the one that had worked. When the option screen opens, I press the Tab button. In the line of text I copied in waitusb=5 after the instruction cde, now all the choices that I have tried so far seem to work. I Hope this helps
