Have you tried a different distro. Not trying to start a distro war here but I've had issues with some distros just not liking certain hardware on install. Toss on a Fedora and see if it has the same failure writing the mbr.<br>
<br>Hmm. before you try that, try killing the existing mbr and reinstalling your buntu version. from a running live CD (if your live CD won't start and it's the latest Ubuntu version that say to me that release won't like your hardware).<br>
