Once thats complete.. Start the mac, then test by shutting it down.. Does it still exhibit the same behaviour?

i have 10.8.4 running on an early mac pro 2009
I bought this computer used, and I think it never had a recovery drive because I have looked for it even in terminal, and I cannot find one. I may just go ahead and reinstall the system anew, this time with a recovery partition. can I install mountain lion by itself, if it was bought in the mac ap store? Or do i need to install lion then the mountain lion update? thank you
it came with mountain lion installed, but i think the computer originally was bought with snow leopard, and the guy who owned it upgraded it. Either way I might have to download Mountiain lion again. I restarted from a time machine backup, which booted to mountain lion of a month ago, and it tirned off with no problem. So its likely this is not a hardware issue, but a software issue having to do with my having messed with the drive too much, in my efforts to increase hard disk space. Is there a way to reinstall mountain lion without first installing all the other ones (snow leopard which i assume was upgraded to lion, then mountXXXXX XXXXXon) Can i just install mountain lion by buying it and not upgrading the others? thank you
i do think it had a recoverypartition, but i mistakenly erased it, because i thought it was part of ToolTech pro (they have this function that makes a backup). So I deleted it when i stopped using tool tech pro, but it was obviously not that. I have restarted, held down command R, and restarted with the option down, and there is no recovery partition. I must have deleted it.
