My third attempt to get the OS upgraded. I have rebooted, cleared the SMC cache, run Disk Utility from recovery mode.
I would really like to get onto Catalina before the next OS hits. Any help would be much appreciated.

We can assume that it is not loading because the download did not complete properly. I suggest you restart, put the download file into the Trash and empty it. Then start fresh and do a new download. Be sure that you are directly connected to your modem/router with an Ethernet cable. Do not use Wi-Fi. Do not use the internet during the download. It can take up to an hour, more or less. Then another 45 minutes or so will be needed to do the installation with several automatic restarts. I assume that you understand that any older 32 bit apps will no longer run under Catalina, if you still have any. Good luck.
