You shouldn't have to do any messing about choosing format etc. An ISO is an image of another CD so basically all the boot information is part of that image you don't have to add it separately. Have you tried a different brand of writeable CD ? My DVD/CD writer hated some writeable DVDs I bought and evrey one I blew was an unreadable coaster. Bought a different brand and have had no problems since.
Pat, I hadn't messed about with formats. One attempt to burn the CD produced garbage, the earlier one, nowt and after two hours of trying to solve the problem last night was about to go to bed when I decided "one more go with a new Mitsubishi DVD"
Imagine my surprise when it actually worked
.
My next hill to climb is another notebook in which Windows imploded but which is a dual boot with Zandros. It is impossible to reinstall MS XP due to a probable bug and hence I cannot find where the problem lies. Therefore, I'm hoping to recover some important Excel files via the Ubuntu installation.
Fingers crossed.
And of course many thanks for the input by our Members. I have learned a lot from your contributions
