Hello and so sorry for the delay! I didn't realize there were responses as the notifications went to my spam mail. I will re-install to the USB and try again. If I get the same problem, I will post back here.

Thanks again!

Thanks for the quick reply 8Gee.

Unfortunately, that was the first thing I checked...it is booting from the USB...

Any other thoughts? Also, I realize that I posted this in Puppy Derivatives instead of in the LxPup folder...is there a way to move it?

I apologize in advance if this has been asked. I searched the archives and couldn't find this in this forum. I downloaded LxPupBionic-18.05+8.iso. I then used DD to put it on a USB to boot from there so I could install it on another USB. I received the message "Operating System Not Found"....
