I need to make a bootable usb drive using the official released iso image for Ubuntu Studio Eoan Ermine 19.10.
I tried MultiBootUSB, dd, Gnome Disk Utility.
MultiBootUSB shows me a message that this is a memdisk iso and not supported.
At the moment, Ubuntu 19.10 looks raw and unstable, there are reports of installation problems. Created the issue on Multibootusb repo https://github.com/mbusb/multibootusb/issues/478.
