I took a photo of the boot screen with my camera but I did not find any way to get the file from my phone to my computer using Puppy directly. Perhaps I had a bad cable.
Luckily, I remembered my laptop has a card reader so I removed my memory card from my camera and inserted it and that worked.
I managed to boot with my thumb drive instead, but unfortunately, I WAS NOT given the possibility to use a savefile option, even though there are two savefiles in the same folder as the OS.
How do I fix that?
