I have 20 dell computers I want to wip and reload op system and all programs. I was thinking cloaning or ghosting. I have read for hours trying to decide what would be the best least exspensive way to do this. I would like to copy one computer to a disk then run it on the rest of the computers. some of the software I have seen only allows 3 uses or the prossesors have to be the same. So on please help! All optiplex and demension these computers are a little different but I can adjust for driver issues after install. ghost the entire HD. I do have key codes for all op systems and office. All other programes are free.
