Had a 521GB fujitsu ssd as system drive for a while, recently got a 480GB Kingston hyperX ssd. Tried to migrate to the faster Kingston ssd. Initially nothing really happened except that the Kingston ssd wouldn't boot after selecting it as boot drive in my mobo bios. But after uninstalling the hard drive cloning hard drive and restarting. When Booting up with my fijitsu ssd, it would stay at the loading screen and then flash the blue screen for a split second and then restart. Got the fujitsu hard drive out and connected to another computer and checked the ssd. The ssd was still working properly. All the files and partitions are still there. Backed everything up afterwards. Tried using windows 8 install disc with auto repair, didn't work, restore system can't find any restore points. Went to cmd prompt and tried the bootrec commands. With Bootrec /scanOS the respons was windows installation:0. Tried using third party software to repair the master boot record. Also did not work. Can someone help me with this problem.

Windows doesn't like to be cloned. Period.

Well, there is a solution to that too. The partition identifiers have changed (and the BSOD is one that says that smss.exe unexpectedly exited, which happened due to not finding stuff where it should be). So updating the mountpoint table in HKLM\System\MountedDevices with the proper IDs should fix it. How to do that? Try using a recovery environment to edit the registry (HKLM\SYSTEM is physically located in [DRIVE:]\Windows\System32\Config\SYSTEM )
