Ok. Hello everybody! First post, first problem. 
So, I had a dual boot of two Win XP Pro SP3. Each Os was on a separate HDD.
I erased the first one and installed Win 7 RC1 there.
During the installation I had disconnected all the other HDD's along with the on that had the 2nd Win XP.
After the installation of Win 7 I lost the dual boot menu and the pc boots directly on Win 7.
I tries EasyBCD to get the dual boot back but here is the problem.
I followed the guide to fix the dual boot but nothing happens.
I managed to display the dual boot menu but when I choose Win XP, the pc reboots automatically. On the other hand, I can boot on Win 7 normally.
So, what am I missing here?
Here are some screenshots that might help:
