Rufus by default installed Zorin in mbr, btw for your infor guys, etcher when we can we shoudl go for that.. What it did to my wokstation that have only zorin 15.3 when I boot to install Zorin 16, is that I see ubuntu on first, on top, then the name of my sdd in second and in tird under the 2 other my usb.. UBUNTU? I tried, its my OS Zorin.. reboot tried the one with the name of my SDD, same OS that boot, and when i try to boot with the usb made on windows 10 with etcher, did not work, made by rufus in mbr and gpt for fun both, did not worked, when i tried etcher on zorin, did not worked either, used the image writer that come with zorin 15.3 nothing..
