Lucid 10.04 and 'Startup disk creator' is fussy which iso's it will pick up. I have tried on my PC, laptop and Netbook all running Lucid and tried several variations of formatting a Usb flash stick using gparted. I have tried fat 32 and fat 16 and have removed lpa(?) and boot flags. I have transfered the download to my 'home' directory and simplified the name of the iso to lupo.iso (yes an Ubuntu derivative).
Yet the software will not recognise this iso but strangely enough will recognise other ubuntu isos in the same directory.

The usb stick was previously set up as a bootable linux Puppy system so I know the stick is OK.

How can I progress with this installation? Suggestions welcome.

Have you verified the iso? If you have, and it verifies, you might try creating the bootable usb stick with unetbootin

Yes, all the downloaded isos were verified but only the Ubuntu isos are accepted. To my knowledge 'unetbootin ' does not offer a persistance and Usb disk creator does a good job (when it works), but thanks that would be an option if I can't solve this problem.

See tips at pendrivelinux.com also.

I like the liveusbcreator too.
