Installer does not seem harddisks

Re: Installer does not seem harddisks

So it is a Karmic bug, related to the dmraid package. One solution is to boot the live CD and choose the first option (try the system without modifications), launch the terminal and do a:

sudo apt-get remove dmraid

Then you can start the installation process. I have tried it and it showed all my partitions.

There are more informations on the ubuntu forums.
