    If the installation is halfway through, you can't and shouldn't cancel it - you will likely end up with a non-working system. If 10.8 is only downloading, though (ie, if you just purchased it in the App Store), you have not actually started installing it yet.

     

    What stage are you at now? What message is displayed on your screen?

    I tried to start the installation but a message said that it was impossible to do because Macintosh has a problem. And now i cant repair Macintosh and I can not leave the installator even restarting the computer.

    Try rebooting from the recovery partition: reboot while holding cmd-R (until you see the Apple logo). You should see the recovery options - you need to select "Install OS X" and follow the prompts. This will not remove your existing user data / applications - it will just reinstall your 10.8 system.

    Your hard drive may be damaged, but if it's only damage to the file structure, this may be repairable.

     

    Do you have a full recent backup of your system, such as with Time Machine? Your best best may be to wipe the drive and restore from the backup.

     

    If not, you may need to get a copy of Diskwarrior and try to repair your drive that way.
