michael_60 :
I loaded windows 7and lost pics. and documet files. How can I find thes files?
Depends on whether the files were overwritten with the new install.
you're probably not going to recover any files. There are several commercial apps that claim to be able to recover files after a format but I've never tried any of them. If you want to google a bit you can try whichever ones you like. Plus when you installed windows it may have overwritten what you are trying to recover. There is a freeware app, Recuva, http://www.recuva.com/download/builds, that has an option to try and recover data after a format but I've never tried it either. If you want to try it I suggest using the portable version so that nothing will be installed on your disk. Google data recovery, and you can select other software to try.
PS: Also look for a folder on your c: drive named windows.old
