Thank you for your reply BurninMan921.
You are right. Your idea would work. Problem is, (long term) I would have to buy the program, since it is not freeware but shareware. Anyway, I think it would be better to spend US$30 on UltraISO than on WinImage.
I am still looking for a way to coax Nero into accepting the .IMG boot floppy format. Strange thing is when it first asks for the boot floppy image location its default is C:\IMAGE.IMG, but when you BROWSE the hard disk for a new location it switches to the .IMA format. Maybe it is just a bug. I haven't had the time, but I am thinking on upgrading my Nero 5.5 to the last version and trying again....
If I find a way, I will post it here.
