I know Linux mint cinnamon can write isos. But I have heard that lots of people use Etcher. Would it be worth installing? Also if I had an os without a VFS (not sure if that is possible) would Etcher provide a "VFS"?
You can use any software like Unetbootin, Gnome Disk Utility, Yumi Multi Boot, xboot, Live USB Creator, etc. to create bootable USB with the help of ISO image file.
Yes agreed, it has been giving a lot of people problems from all the topics I have found on it.I'd avoid Unetbootin for the time being. Well, for the past year or so.
