[Bug 1747329] Re: Workaround needed to boot from USB stick - "gfxboot.c32: not a COM32R image"

[sudodus]

Extracting tools can be affected by this "gfxboot.c32: not a COM32R
image" bug. It is a problem of the tool to create the USB boot drive,
and should be fixed by the developer of that particular tool.

-o-

Cloning tools are not affected by this bug. You can use Ubuntu's Startup
Disk Creator alias usb-creator-gtk in Ubuntu 16.04 LTS and newer
versions, or Disks alias gnome-disks, which both are GUI tools with a
final checkpoint and they are packaged with Lubuntu. You can also use
mkusb, which can be installed from a PPA. mkusb can clone, but also
extract and create a persistent live drive.

As mentioned by Steve Langasek, you can also use dd, but it is risky,
because it does what you tell it to do without questions and many people
have overwritten valuable data after a minor typing error or some other
(minor?) mistake.

Title:
  Workaround needed to boot from USB stick - "gfxboot.c32: not a COM32R
  image"

Status in syslinux package in Ubuntu:
  Invalid

Bug description:
  So, last night I downloaded the latest daily build of Lubuntu 18.04 from here:
  http://cdimage.ubuntu.com/lubuntu/daily-live/current/
  Checked 256SHAsum, all OK. Created USB boot stick.

  Got the same error message as listed in the below post:
  https://askubuntu.com/questions/486602/ubuntu-14-04-lts-live-usb-boot-error-gfxboot-c32not-a-valid-com32r-image
   - The fix mentioned in that post worked for me (upon getting that message, press TAB, type "live" & press enter.) 

  Installing on a 2005-era Dell Latitude D610 laptop, 1.2GB RAM.
   
  Thanks,
  Ken.
