[Dev] Install image fails

I'm not sure this is the place to post but I don't have any other options. I followed the instructions for the install pen drive creation and got it to run but was given no choice for a drive to install on. It chose the hard drive without telling me, wiped the drive and failed to install anything leaving me with a boat anchor. I had to install Windows 10, as there was no recovery partition left from the original 8.1 install. The live image fails to boot. So far I can't say I'm very impressed. Any suggestions appreciated.
