  1. Was reading somewhere that if you don’t have the UEFI and Legacy only then on the Partition Scheme use the MBR instead, I tried it with the GPT and it didn’t work for me, so now I’m redoing it and using the MBR scheme and hopefully it will work this time, and it takes a long time for Rufus to complete the image on the USB, on my system anyhow, Dell workstation T3500 with an Intel Xeon 6580 I recently installed.
