Ok..

I follwed step by step (http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step). I got as far as the "NFTS Boot Sector Recovery " section. It let me go as far as the write and then told me I needed to reboot. I tried to reboot normally and now get a loop of new splash screens, HP setting up recovery screen, then a blue screen, then it loops and loops.... I finally reinserted the REATOGO disk and got that to load.... "Invalid Partition Table" error message gone but now this infinate loop of splash screens, etc....
