Questions about migrating OS from HDD to SSD

Question One: "I built my computer with a 500GB hard drive, the boot times are slow and I have an extra 64GB Solid State Drive. I want to know if there is a freeware which can help me migrate my OS and a couple of other applications onto the SSD just for the faster boot times."
Question Two: "I already have a standard HDD with Windows 7 and tons of games, video, audio on it. I wonder if it is possible to transfer the OS only to the SSD and keep everything else on the HDD without having to reinstall them."

Due to the SSD advantages over HDD, like faster reading/writing speed, no moving parts inside, resistance to share and damage, etc, users want to migrate everything, especially the OS, from HDD to SSD. To get around the hassles of reinstalling OS and other apps, the best solution is to use free HDD to SSD migration software. That can help you move only OS partition or all partitions from HDD to SSD without reinstalling all. Then what’s the best HDD to SSD migration tool?
