I can confirm that I experience this same problem, after trying to boot Ubuntu 16.04 from a usb-stick, which I created on an Ubuntu 14.04 system. Pressing TAB and selecting live from the menu doesn't help.
So I think that sudodus is right. I guess I have to wait for an update for my 14.04 system, before I can use it to create a working usb stick. Installing from a DVD doesn't help either. The newest usb-creator-gtk in the repositories is 0.2.56.3, which was probably used when creating my usb stick. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1325801 Title: failed to boot from USB disk with error: gfxboot.c32: not a COM32R Image boot: To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-cdimage/+bug/1325801/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
