How to solve the problem with the transition c HDD to SSD (MacBook Pro mid 2012)?

Background.
I decided to change HDD to SSD on MacBook PRO mid 2012 because the HDD was slow.
Did everything according to manual: dismantled; changed HDD to SSD; HDD put in an external box and hooked up via USB, copied the contents of the HDD to the SSD with the built-in utilities.

Everything turned out the system was booted. However, after the first shutdown and re-enable system with an SSD will boot failed - the Apple, the progress bar and then turns off. Tried to reload several times, but nothing has changed. Then tried will boot from the old HDD connected via USB, I get almost the same thing - the Apple, the progress bar, but this time an endless ring download.

Decided to copy the contents of the HDD again, but now built-in utility complains with errors: "could Not validate source error 252", "could Not validate source error 254". Immediately after that, I decided to check the disk for errors. After verification utility error, saying that there are problems. After trying to "Fix" swore already that fix disk not. I want to note that before you upgrade to SSD, I checked the HDD and no errors.

Prompt in what side to dig and what to do?

PS I Tried to put a clean system on the SSD everything is fine but the problem is that I need a copy of an existing HDD system.

TimeMachine as an option ?

You need not to copy the info and create a backup through TimeMachine! Then booted into recovery mode and restore the backup from the backup on your SSD.
