Ubuntu 10.10 on USB Drive does not boot

Have you checked the USB for consistency? You can do this once the USB starts to boot by pressing spacebar when you see the stickman.

"the Bios reports that the Kernel is missing": BIOS doesn't load kernel.
Could you provide an exact report of what happen (exact error message).

  The problem is different :

The USB port of the Win7 Toshiba PC with N450 CPU works fine and loads
other distributions of Ubuntu other then Ubuntu 10.10. I have seen on
the web the same claim as mine from others.
The PC shows the following message :
graphics initialization failed
error setting up gfxboot
boot:
Take into account that the PC has a small monitor with only 600 px
vertical resolution.
The warning states that a graphics initialization has failed. I wonder
if the problem is related to the specific screen resolution, or not.
In any case, after that, it does not boot. Lubuntu 10.10 has no problem,
but appears as a much less comprehensive distribution then Ubuntu 10.10.

A guy in Internet, replying to another guy who has exactly the same
problem, said to type help at the boot prompt and said that, after doing
this, the boot was regular.
I tried but it does not work. The help menu appears but no option,
apparently, can make the boot working.

Any further idea ?

Thanks for help.

  The problem is as follows :

The USB port of the Win7 Toshiba PC with N450 CPU works fine and loads
other distributions of Ubuntu other then Ubuntu 10.10. The same USB
drive loads perfectly on another much older notebook PC with Centrino
CPU and Windows XP.

Please don't post with previous message.
I found the answer you talk, but anything else.
And unfortunately gfxboot is a software I don't manage.
What is the graphic card or processor ?

  The processor is 2 x Intel Atom N455 1.66 GHz ; RAM memory is 1.015
GByte; BIOS is Toshiba Ver. 1.60.
The display controller is Intel N10 family integrated graphic controller
with 512 KB memory.

The point is that the USB loads other versions of Ubuntu (Lubuntu), not
Ubuntu 10.10, and the same USB drive however boots on another PC.

My doubt is that screen resolution is 1024 x 600 px and I wonder if the
Kernel is compatible with such resolution. I would expect an error after
booting, however, not before booting.
Given that the boot sector is there in the USB drive and works on
another PC, why the N455 processor does not read that boot sector on
that USB drive ? I read of others having the same problem with the same
PC and same Ubuntu release.

Thanks for any help.

Same as
     https://answers.edge.launchpad.net/ubuntu/+source/gfxboot/+question/129790
and unfortunately no solution.

http://ubuntuforums.org/showthread.php?t=1594003
    Upon encountering the error, simply type "help". Installer proceeds to load as expected.
https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/659253

Note that the "help" or "live" doesn't seem help if you've a RW_LEGACY flashed Chromebook on Braswell machine where there is no video BIOS. I don't have a solution yet though.

I updated a comment in bug #1530530 - I was able to boot 14.04.4 LTS written with _unetbootin_ (since it replaces gfxboot with its own boot menu.
