    Did the system originally come with OS X Lion or greater? If so, you can use Internet Recovery to reinstall the OS.

    Different Mac models may require different methods to install OS X, and you need to provide enough info on your Mac model before anyone could help you. As the previous post implies, if you have a recent model with Internet Recovery built in, it's much easier than older models to reinstall OS X.

    As a general rule if the machine is newer than 2011 then it will have internet recovery built in so you can recover by pressing Command + R at startup.

    If the machine is older than 2010 then it will need an OSX install disk, either the original grey machine specific disk or a newer retail version (retail versions released prior to the machine won't work).

    There is also a period around 2010-2011 where old Macs were given firmware updates to allow them to perform recovery the same as the newer models, however you need to have purchased Lion on your Mac App Store account for it to work on these machines.

    As above, Command + R should start the internet recovery service.

    So you can go in to Disk Utility?
    You should be able to format the disk as Mac OS Extended (journaled).

    Edit - it may be detecting the mbr. The disk needs to be formatted in GUID partition Table.

    I first tried to remove partition but after 20 min it is still "preparing to remove partition" . there is no option to cancel . Should I reboot ?

    EDIT : I canceled and formated . Installing now . THanks !

    No, I wouldn't think that would be a good idea. Let it finish what it's doing, if possible.
    I would have thought you should be formatting the drive itself, not a partition.

    Actually it worked . Now I have a 10GB partition for recovery and the rest ( almost 740GB ) for OSX ... until now! I havent gived up installing linux ( lubuntu is my personal favorite distro ) . This time I will install EFind first . All this is problem was actually help.ubuntu fault ! the tutorial there didnt mentioned EFInd nor another EFI bootloader at all !
