My Mac isn't booting

i have updated my OS X 10.7.1 to 10.7.2 using a software on utorrent,

after restarting my MBP a scree appears telling me to press the power button for a restart ( in many languages)

i tried restarting but it isnt working,

when pressing the option key i can boot using bootcamp and windows 7 is working fine.

The problem is that i ldnt have any startup disk or something like that and time machine is turned off.


I appreciate you help

Never use a torrent download of a software update!!!!!! It was more than likely corrupt! Apple supply the update downloads for free from the Apple site. Use those. Someone will come and hopefully get you out of trouble if it's possible, just be patient.

when did you buy a mbp?

If you buy with Snow Leopard you have a Mac OS X instal DVD, but you buy with Lion try:


turn on the MBP, when the BONG, press the option(alt) key, and select the Recovery, format the drive, and install the Lion agin...


But you have a Mac OS X install DVD, insert the DVD to the Superdrive, and reboot the computer, when the BONG, press the option key, and select Mac OS X INSTALL DVD, format the drive, and install the OSX Snow Leopard
