I assumed we were talking about the discs for operating systems to be loaded into VM. Or am I mistaken?
The discs that I have with OSs on them, Deacon, are the discs sent by Dell with the computer (actually, they no longer send the discs unless you complain to them, as I did with both XP and 7). Labeled "For Distribution with a new PC" or that equivalent. These discs show up on the system info page like this: "Windows is activated, Product code is 00359-OEM-8994547-00095" Unfortunately, using this disc to install Windows in the VM brings up the "Enter Product Code" page which has 5 boxes for 5 digits each. Didn't matter which OS I installed, they all asked this.
When I called Dell, they told me that the OS was specific to the machine it came with and if reinstalled on that machine, that page would not come up. OSs were not transferable to another machine. Since I have never updated an OS to a newer version, I don't have a disc that is store bought. And since I have only purchased thru the college purchase program, I only have dell machines.
In any case, I have loaded XP, and since there is a built-in 30 day time period to use the OS without registering, I have tried it out. Some things work, however older programs all seem to have something not functioning. (For example, a dos era cad program, which worked well in XP thru a Command Prompt window, opens into 1/9 of the screen while whiting out the rest of the screen, and the mouse only works on the bottom left quarter of that smaller screen shifting to the white area.)
I will load Win95 into VM and try them (older ones) out in it. If I can get some functionality out of them perhaps I can work with that to transfer data to something more up to date. Very tedious, but possible, and better than lost data, however time consuming.
At this point, I have spend over 40 hours on this issue, and work I get paid to do has piled up with no little irritation to others.
Again, Deacon, thanks for your help and the tip about VM
