I can confirm the problem. I tried writing the disk on a Win 10
machine, and it threw an error that the source would not fit on one
l disk.

Now, Poly, the price of a DVD drive is minimal. Why not just swap out
your antic CD-ROM drive and install a DVD. You don't have to go the
Blue-ray route, unless you want to.

If, for some reason you cannot fit it into the case, just get an
external model. Problem solved.
