Creating a USB bootable version of Ubuntu from the Startup Disk Creator (other) and attempting to boot, I was greeted by the error above. It might look a bit scary but it’s really easy to fix, just plug the USB flash drive into a computer.

Solution i:

1. Open the the syslinux folder in the root of the flash drive.
2. Inside is a file called syslinux.cfg you’ll want to edit that.
3. Find the line “ui gfxboot bootlogo” and simply remove the “ui “.
4. Save and try booting again.

Below is how my syslinux.cfg file looks after editing:

# D-I config version 2.0
include menu.cfg
default vesamenu.c32
prompt 0
timeout 50
gfxboot bootlogo

Solution ii:

it looks as though there is another way of fixing this issue if there is no “ui” in the file, this is to do as followed (as pointed out in the comments below):

1. Type “help” and press enter
2. Hit Enter again

This should boot correctly and shouldn’t need to be done every time.
