Why does booting from Live-USB give me a 'cant find vesamenu.c32' error?

CONFIRMED:

  • error message= "Could not find kernel image: vesamenu.c32"
  • error occurs for 11.04 and 10.10 ISO files. 10.04 or below don't have this problem
  • problem also affects all other Ubuntu-based images like Kubuntu, Xubuntu, Mint,...
  • Problem occurs with pendrives created with pendrivelinux's universal usb installer as well as with unetbootin. This leads me to the conclusion that the problem may not be in these tools but in the image itself.

STEPS TO REPRODUCE:

  • download 11.04 alternate installer iso from ubuntu.com
  • check download with md5sum
  • create a bootable installer on a pendrive with either universal-usb-installer (Windows) or Unetbootin (Linux)
  • boot with the pendrive

WORKAROUND:

  1. Copy all files (only files, not directories) from the root (/) of the pendrive to the /syslinux directory of the pendrive.
  2. Do NOT overwrite files that already exist in the /syslinux directory
  3. Boot from the pendrive: no longer any errors.

Solution 2:

doesnt work for me 12.04.1 desktop amd64 and universal usb installer 1.9.1.9

i copied * from /syslinux to /boot then it worked
