i would like say thanx to icchansan for help...
after 20 times (of software reinstalling) that mac os x won't to start (no more) on my HP elite....
was enough to say : "listen stupid machine... if you don't want to start i call my friend icchansan... and than will be big di*k for you..." after that not only start computer, but i can do also time machine recovery.

could you think that i must keep your photo on the desk near hp ??? is something happen....

ps: seriously.. i don't know what happen but after 20 times... now seems to works

Next step will be SNOW LEOPARD upgrade... anyone can tell me how to do in a safe way ???

Thanks to all !
