I installed Zorin OS on my girlfriends work computer. The installation went well but she wasn't using it so I wanted to use it, so I installed puppy OS on there since I'm mor comfortable using it, which installed nicely. So" someone" got jealous and wanted to use it but don't know how to use puppy. So I put Zorin back on it and it installed well but will not boot from the hard drive. I'll give more details once I get home.
