A few months I decided to install Ubuntu 12.04 on my PC alongside with my Windows 7 partition. In order to do that and avoid any mistake, I followed these steps:

Everything was going well until I decided to update to the 12.10 realese. I don't know what happened, but after I updated my Ubuntu, it stoped working, it didn't even launched, when I turned on my pc and choose to run "Ubuntu 12.04" on the Grub Screen, a weird messaged appeared.
Well, so I decided to install the Ubuntu 12.10 and forget about the 12.04 partition, no problem. I erased the partitions used for the Ubuntu 12.04 with EaseUS partition Manager.
However, when I start my PC, there is still the option of "Ubuntu 12.04" to chose, is that bad?
And what about now, can I use the Windows Installer of Ubuntu ( http://www.ubuntu.com/download/help/install-ubuntu-with-windows ) to install the Ubuntu 12.10 ? What should I do to have Ubuntu 12.10 and Windows 7 in dual boot again?
