How to make SSD Drive bootable from a disk utilies restore My mid-2009 mac book pro hard drive is dying so I bought an SSD to replace it.  I tried plugging in the ssd drive to the mac via a usb to sata connection and using SuperDuper to copy the contents (saw a video and it looked easy), but it took forever and I got a generic input output error.  Next I tried restoring from a time machine backup to the ssd drive.  picture an external hard drive with the time machine backup connected to my mac book via usb and my ssd drive connected to the mac book pro via usb. I went into Apple Disk Utilities and did a restore from the external hard drive to the ssd drive.  It took about 16 hours, but it completed.  So now I have 2 drives with the same information - at least I think.  I wanted the ssd drive to be bootable, but it's not.  Can someone explain what a restore really does and how I can make the ssd drive bootable so that I can replace the dying, old mac book hd.  Note: I want to make the ssd drive internal and not keep it as a bootable external drive.  Thanks!
Steps I followed to solve:
Downloaded El Capitan to Ssd drive
Removed old drive replaced with SSD drive 
Ran migration utility from time machine backup
Rebooted and working great. Thanks for the help!
