Ubuntu 10.04 not booting from USB Stick

[Blackbelt2011]

Hi,

I have a Live-System Boot DVD with Ubuntu 10.04.
There is a utility installed on the DVD to create a new boot medium.
I plugged in a new empty Kingston 4GB memory stick (the system uses 3 GB for itself), and it was found by the utility program.

I can see that there are probably all folders written on the stick: .disk, casper, desinfect, preseed, syslinux, and the files urdrive, unInstaller and casper-rw.

But when I try to boot from this stick, there is an error message "vesamenu.c32: not a COM32R image". I don't know what this means.
then there is a prompt: boot: but there is no booting.

I want to keep this special DVD from the c't magazine, because it contains 4 virus scanners. Can anybody give me a hint to boot a Laptop from that stick? With the DVD there is no problem, but on the USB stick it does not work.

Thanks

Hi, I have searched a bit for you and i found this 2 solutins (but i can't guarantee that they will work)

#1

Type "Live" and enter. Linux should boot up normally

#2

copy vesamenu.c32 from Ubuntu live USB. The USB now boots.

I entered live at the boot prompt, but the system does not start.
As far as I know there is the kernel vmlinuz must be started first?
Linux shell commands as "ls" do also not work at that prompt....

I do not understand the message of the vesamenu.c32 file, because the file is on the stick in the folder isolinux as well as on the original DVD in the same folder isolinux. The size 144KB is the same.

Maybe I try to write the stick again just on another machine...

Have you tried to copy paste the file from dvd to usb ? Might be corrupted

Generally a ISO loaded to a usb thumb with the correct tool should boot.

Did you extract the dvd, then use a utility like unetbootin to load the thumb?

I believe you would have to have an ISO with unetbootin, there are a number of usb flash loaders.

Do you have a link to this dvd for info?
