Power down phone. Power up holding volume down and End key. If you are rooted you will get a white screen with 3 options. One of those options is to press home for recovery, press it and you will either get the htc screen w green words or you will get a phone with an exclamation point. The ! is a sign that you don't have a recovery image installed correctly. The words is a great sign, continue with back up from nandroid. Oh and don't partition your sd card until you have backed it up!!
