I did a Wubi install of Ubuntu 12.10 in Windows 7. It worked properly, but now, when I try to start the Ubuntu, it shows me the Plymouth, but nothing more. I waited for very long time, but nothing happens.
Maybe the fact that before the first time, when the problem occurred, I forgot to eject a flash drive can be of some help.
I also run the
chkdsk \r command but it didn't help.
