Instalation hanging after "system requirements" screen

[oscarfh]

Hi,
I am trying to install Ubuntu on my machine, the history is the following:

I have a dual boot computer with Windows 7 and Ubuntu. Yesterday I turned the computer on and tried to boot on Windows, it then showed that "repair" system.
It started repairing and failed with an I/O failure.
Since then I have no GRUB, so I cannot boot.

I then ran Ubuntu LiveCD, it booted perfectly. I can mount all the partitions and so on, but I noticed that the Ubuntu partition was corrupted.
I tried to reinstall Ubuntu, the installer loads, I choose the language, click next and the page showing the requirements appear (4.5 Gb, Network access, etc).
If I click "next" in this screen, the CD runs, the HD light on my computer turns on but nothing happens. (The mouse cursor will stay this round image forever). I let it running for hours and nothing happened.

How can I check what is going on? Is there any other way to install Ubuntu?
Could that be a physical HD problem? How would I troubleshoot it?

ps: disk utility SMART status is green with "a few block errors"

Thanks,
Oscar

with some hardware, sometimes boot option is required (google around : "ubuntu boot option")

I already have the partitions (ubuntu was already installed in my machine)
I boot using the liveCD and select "install". After that there is that screen where it detects if I have 4.5gb and so on. Everything is green.
After clicking "continue" everything hangs up
