    I recently tried to install the new OS X maverick, but about 4 min into the process it told me my disk needed to be repaired. That I should back up my stuff and restore the drive.

    I will do that, but I would like to just return my computer to its previous state. Is there some way to stop running the OS X install when my computer re-starts?

    Thanks

    Not too much information here about what (OS version, Machine type) you are starting with. So, Guessing:Try holding down the option key at startup. I'm not 100% sure that will work in this case, but if the computer has a recovery partition and/or is recent enough to do internet recovery, it should work. If it's older, put in a DVD and press the C key (no DVD drive - it's probably "newer" in the scale I'm using)

    Partition the drive...install OS A to one partition, OS B to the other. Hold option when booting to select which OS you want to boot from.

    i prefer to install 2nd MacOs on external disk (preferably with Firewire 800 connection), unless my machine has got more than one disk.

    you didn't mention your computer model and the MacOS you want to install. MacOS 9 and 10? 10.5 and 10.6?

    you didn't mention why you want to install 2 MacOS. do you want to run a "repair" utility from the 2nd OS?

    Use VirtualBox and run one virtualized inside the other. The virtual one can be kept on your main HD, an external drive, USB key, etc.
