I want to install Ubuntu 9.10 on a PC which already has Windows 7 installed.

I have set up an unformatted primary partition with GParted and Ubuntu live:

During the installation I choose language (I'm Italian), time and keyboard, and then it shows me the "prepare partition" window, with no partitions at all and all greyed out!

Do you have any hints?

This is strange, as I assume you are using the same liveCD for both partitioning and installing, right? So I don't see how comes the system sees your HD on the first case and not in the second. Did you reboot the machine between partitioning and trying to install? If not I would first try that.

As a second option (this is not really a solution but a possible workaround) I would try the alternate install CD (available on the ubuntu website) which is text based.

Is there anything particular about your HD configuration? (Like virtual volumes or raid configurations?).

yes, same liveCD for partitioning and installing, and i've rebooted many times to try that :(

No raid configuration, a one only SATA hard disk.

i've installed 9.04 and it works perfectly, i see all partitions in the partitions window :|

so this thing is a bug of Karmic (9.10).

then i've upgraded to 9.10, everything works now
