Hi Mumbodog,
sfc /scannow did not fix the problem

The computer had several viri that I had cleand off and they had probably killed the registry. Everything I tried was not able to fix the problem
However, I did find out that the HP recovery works very well now. It left all the user data intact and fully accessible
So, I got the system running. Although I had to reinstall some apps, the data associated with the apps was still in the default locations and fully accessible.
Thanks for your help, Jim
