no usually if your recovery partition is gone, you would be required to reinstall u r recovery software that came with your computer, if you don't have the recovery dvd then you'd have to buy a new one, or if you have the software for you operating system such as XP Vista etc!, you can just re install it, and search for drivers on the mfg web site for your computer.
But all data you had on you hard disk will be lost eather way!
If I can be of further assistance send me a request, I would be pleased to assist you in anyway I can.
