How To: Fix “Unknown keyword in configuration file.” Ubuntu USB Boot
Attempting Boot From USB Device

Unknown keyword in configuration file.

After creating a USB bootable version of Ubuntu from the Startup Disk Creator (or usb-creator-gtk) 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 (windows or linux, mac too probably but I haven’t tried that.)
Solution 1:
- Open the the syslinux folder in the root of the flash drive.
- Inside is a file called syslinux.cfg you’ll want to edit that.
- Find the line “ui gfxboot bootlogo” and simply remove the “ui “.
- 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 2
Alternatively 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):
- Type “help” and press enter
- Hit Enter again
This should boot correctly and shouldn’t need to be done every time.
