I want to install Apple Mac OS on my HP 630 notebook, is it possible, or there will be any problem in future.
It is possible - do a Google for 'Hackintosh' - but there are quite a few hurdles to overcome, mainly to do with driver issues and which version of the Mac OS you are using and, yes, there probably will be issues in the future, don't expect it to run as smoothly as it would on an actual Apple machine.

Check the HP support website for drivers for your model.
If they don't have any MacOS drivers for it, it's no good installing it because the sound and graphics and other components will not work without the proper drivers.
"Windows 7 Ultimate 32-bit (not genuine)" Not genuine? Why would you put that in your specs?
