I had this happen as well. If it does hold vol up, and press the power button. Your SD card is not compatible, and you need to try a different one. Make sure you format it on the computer before you start (not quick format). Once you obtain a new goldcard, you have to do step 2 over again. Remember to remove the old goldcard from the hack kit, and replace it with the new one before begining. I had this happen to me and that fixed it, now I'm rooted and loving it. CM7 is amazing. Hope all this helps.
