I'm running Ubuntu 11.10 on my Macbook Pro (Late 2009) as the only operating system, so theres's no Mac OS X oder Bootcamp installed. It runs fine and now i'd like to create an image of the current installation.
Unfortunately my Acronis True Image cd doesn't boot on this device and my attempts to create an image with partimage or dd from a bootable ubuntu live cd to a external hd failed ("can't read from block 0"). Are there any others out there with such an installation and if yes: how did you succeed in imaging your partition/device?
What is the DD command you're trying from the Ubuntu live CD? I've had success with that method, on a similar model of MacBook, using Puppy Linux 4.3 as a live CD. I don't know if it matters, but I also have rEFIt (http://refit.sourceforge.net/) installed in my firmware.
