no, i installed the HD in a different machine and it worked fine, however when I put it in another machine, it doesn't boot further, I ran the HD test and it came up with no errors.
Does the PC let you switch out of the graphic screen? Should be a ubuntu safe mode you can choose to boot. maybe see more info what's going on. i.e. kernel panic or something to that effect.
Press Alt+F1 when the loading screen appears [it'll drop you to a console where you can see what's going on] and post any error messages. Then we can probably get an idea of what the problem is.
