Bas, do not know if you have a Karmic partition in your hard drive with 
grub2. If you do, please boot from the hard drive Karmic, with the usb 
drive inserted, check the following.....

When grub2 boots (from the hard drive), go to grub2 shell, and type
ls

note the notation of that usb, eg., (hd2,1)

boot that karmic (again from hard drive), mount that usb drive and check 
if (usb)/boot/grub/grub.cfg is there. (may not be there from the error 
message you get). Also note UUID of usb from blkid command.

Amend or add a grub.cfg to that (usb)/boot/grub/grub.cfg.
Copy from your (harddrive)/boot/grub/grub.cfg

Amend the (usb)/boot/grub/grub.cfg as follows.....

just after the d/00 entry and BEFORE the d/10 entries,
amend the lines to the usb (hd2,1) and UUID number,
example below...

> set root=(hd2,1)
> search --no-floppy --fs-uuid --set 121658db-a541-4f6a-b5b2-2e626754c197


Also, just after the d/10 entry, again amend to the usb (hd2,1) and UUID no.

example...

> 	set root=(hd2,1)
> 	search --no-floppy --fs-uuid --set f3412cbb-51f9-428e-9ef9-1cfd34c59a60
> 	linux	/boot/vmlinuz-2.6.31-16-generic root=UUID=f3412cbb-51f9-428e-9ef9-1cfd34c59a60 ro   quiet splash
> 	initrd	/boot/initrd.img-2.6.31-16-generic

Save, done.


If it still does not boot, at grub2 (this time it should be from your 
usb) you do a 'ls' again and note that (hd,x,y), it may become for 
example, (hd3,1) - usb are known for doing that.

Bas, in case you don't have Karmic at hard drive, I suggest you 
reinstall (not copy image) direct to your usb drive and set grub2 to 
that usb. Boot using esc, F12, F8 or F10, whatever the case for your 
computer.

One note from my experience running kubuntu from usb....
it is extremely slow..., it is not worth the effort. Running dsl linux 
or puppy linux from usb is fast and good; very different from running 
kubuntu or kubuntu netbook remix from usb. (may be good for internal 
flash drives)
