Ubuntu 13.10 is stuck after "Prepare" step

[Telma Woerle de Lima Soares]

I am trying to install ubuntu 13.10 on a sony vaio SVE14AFBB with windows 7 and uefi system. I could mount the windows and sony system partitions on trying ubuntu. But when I go to installion is stucks after the prepare step. It recognizes that is necessary to unmount partitions, I select yes and after this the installation stucks with the waiting mouse pointer.

I am think it is a bug because it also affects other distribution.
