Here are the requirements for Mountain Lion:

Did you purchase Mountain Lion? Recovery only works if you are reinstalling.
Did you purchase Lion and are you able to use recovery with it? Using recovery means you restart holding down Command + Option + R (that's for internet recovery = connects you directly to Apple's servers).
yes i have just purchased mountain lion from app store and i did purchase lion and i can use the recovery with lion i just wan to upgrade to mountain lion from lion not a clean install.
Try booting into the Safe Mode and see if it will install there. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application unistaller. For each disable/delete, you will need to restart if you don't do them all at once.
What is the exact, complete text of the error message?
os x cannot be installed on the disk, because a recovery system cant be created. visit apple website
One possible cause of this error is a Boot Camp volume that has a name beginning with a period ("."). If you have such a volume, rename it. Otherwise, follow the instructions linked below:
OS X Lion: Installer reports "This disk cannot be used to start up your computer"
I deleted the boot camp partition and gained the original size of the disk
And can you install now?
No I don't know what to do
Deleting the Boot Camp partition is not what's suggested in the support article. Did you follow those instructions? Also, what backups do you have?
I didn't follow the instructions and I don't have any backups
Before you proceed any further, I suggest you make a backup, preferable two either using Time Machine and/or a cloning program.
I didn't follow the instructions and I don't have any backups
What kind of help are you asking for, exactly?
mountain lion cant install no recovery
