The need to clone only OS to SSD

I recently bought a new SSD drive and want it to be my Windows 7 system drive where i just save all my Windows installation and some programs & games, so that my boot speed and app running speed are faster. The SSD is 120 GB and the system partition is 150GB, but only 50GB are used, so there is plenty of space. I don't know if it's safe to clone this partitions to SSD, or if it's possible to clone only OS partition but not whole HDD?

Answer: as we all know, simple functions of copy and paste can not be used to transfer the operating system and some applications. Because the applications or programs may not work normally after transferring.

Some users may choose Windows built-in "Backup and Restore" to clone OS partition to SSD. It means that you need to first backup system and then restore it to new SSD. Between these two tasks, you need a place to temporarily save the system image file and this place should not be small in size, so this will be time-consuming and boring task.
