Comment 16 for bug 1038522

This is happening to my clean install (well, my try) of Ubuntu 12.10, 64-bit on a machine that already has 12.04. I want to overwrite the root partition, keeping the /home as is.

It happened when I installed 12.04 too, but I somehow managed to make it install -- can't remember, but I thing a few reboots and the partitions finally showed up. Not happening now.

The install steps:

- start computer with USB key on, boots fine into Ubuntu (I tried both the "Try" and "Install" options);
- if I choose to install, it first goes to the language selection (English)
- then to "preparing to install Ubuntu", where it approves both my free space and Internet connectivity;
- next, come the surprise: instead of going to a screen where I can choose whether I want to wipe the disk, install along other OS, or do manual... I go straight into the manual install screen;
- and there, as other people reported, there is nothing on the top area where partitions should be.

The HD is seen, listed as /dev/sda. If I choose th "Try Ubuntu" option, I also see the partitions, can mount them and see their contents.
