Ubuntu – Cannot boot from USB disk with “not a COM32R image” error


After installing 11.10 on my Dell Studo 15 (Model 1557) laptop, it started to overheat. Recently it even shutdown twice saying that critical temperature has reached even when I was just idling (not even a single program was open except for Firefox). After learning that it is a problem with 3.0.0 kernel I decided to roll back to 10.04 LTS. I have downloaded the most recent 10.04 iso from ubuntu.com and created a live USB using startup disk creator in 11.10.

But when I am trying to boot from USB I am getting the following error

vesamenu.c32: not a COM32R image

I have installed ubuntu from usb stick a couple of dozen times before this and I think it is not a problem with my hardware. Please tell me what to do.

  • I recently had this problem and I solved it this way:

    • hit "TAB": the installer will show a list of possible images
    • type the correct image name (watch caps!)
    • hit enter
