Hi.I managed to install snow leopard 10.6.3 on my dell latitude e5500 and work almost perfect.Unfortunately I made many tries to install Mountain Lion using myhack but the installer does not see any hard disk.I put the disk in an hp laptop and I managed to install ML but when I put the disk back I got the "Still waiting for root device" message.As soon as Snow leopard work why I can't install ML?
