Does SSD register in BIOS now?
Does it still hang on the Starting Windows screen? Is this the old OS or the new install attempt?
Try booting the DVD Repair console or Repair CD to run Startup Repair a few times. Post back results.
Go back over all of the troubleshooting steps given so far to make sure each has been done, or ask back questions needed to get them done. Then we will have more steps.
Do you have another computer to install Win7 to the desired SSD/HD if necessary then SysPrep it to move back to problem hardware?
