Hello, it's been a bit since I loaded the OS. I do not know why it went in as "Legacy", but I would like to change that to EFI. I will also be dual booting with Unbutu 18.XX. WHere did I go wrong? I know I fiddled with some settings before loading & probably screwed up. So, should I: 1. Change settings/update firmware? 2. Update firmware (Should bring all settings to stock)? Then Ubuntu18.XX or Windows first? I will be using Windows mostly. I will probably put a couple other Linux distros to experiment. This will be controlling a Software Defined ham radio transceiver. Thank you, Ed
