Do you have the possibility of a connection to the internet, while installing? If so, try downloading the
mini.iso from
http://archive.ubuntu.com/ubuntu/dis...mages/netboot/. This is a image for a netinstall version of Ubuntu/Kubuntu/Xubuntu. The image is tiny (8.8 MB).
I've experienced, that a normal installation doesn't work sometimes, but it works fine with a netinstall.
A little Plus is, that your system will be totaly up to date, as the newest packages are downloaded for the installation.
If you can't connect to the internet while installation or if this doesn't work, we'll have to try something else.
