I have a YUMI multiboot installer USB stick and I have installed Linux Mint, Ubuntu, Fedora Games, Windows 7 and Windows 8 successfully from it. I also have three different anti-malware tools and Parted Magic in this single USB stick.
Debian is the only one giving problems. When I boot from debian-live-8.6.0-amd64-gnome-desktop.iso I get the error "The CD_ROM does not seem to contain a valid 'Release' file, or that file could not be read correctly" right after selecting language. Same error occurs in Install or Graphical install. Live desktop runs perfectly. "Install Debian jessie" shortcut does nothing or flashes some window so fast, I cannot read it.
How do I get Debian installer to work from YUMI multiboot installer?
