So that's why the Mac Mini not booting up properly ...

I came back home from a one month trip, and this first thing I did  was  turning on my Mac Mini running Windows 7, cause nothing better than turn on your faithful machine and get back to your regular geek life, and that's when I found out that the MacMini couldn't boot up successfully on the Windows 7 OS.

After tried and tried and tried, I finally found out why it was not working: the 1.5Tb harddisk was not working properly on the external dock. Once I reboot it and get it working, everything is back to normal.
