Is there any way to burn ISO files without a DVD burner?
That depends on the file format of the ISO and size of the ISO.
If it is formated to fit a standard CD,(700mb) then yes, a standard
CDROM writer/rewriter will do just fine. , but if it is a DVD ISO
(anything over 715mb) or if the original was a DVD ripped into an
ISO, then no. you must have a DVD burner to write it.
Now, having said that, there is a way to open the iso and
separate it into several CD's. WinISO is a good program because it
will expand any ISO, DVD or otherwise. But, if the DVD ISO is a
program, or a movie, a TOC or "table of contents" will determine
what is supposed to be in the program/movie, and it may not work on
separate volumes/CD's.
Another program that burns .iso files is Clone CD. Once again,
if the .iso is bigger than your standard 700mb CD will hold, then
you will need a DVD burner.
