Thanks George or Mary I tried what you recomended and finally got to this point >volume in drive c is MS-RAMDRIVE < directory of C:\ File not found !,,837,568 bytes free. Then I Tried C:\.Format got required parameter missing. But the good news,I think is that now my boot disk works. This has become a pet project so I'll keep pluggin away.
