All you require here is a Recording Application like Nero and use the Copy CD option.
If it is a DVD that you need to copy you just use the Copy DVD option in the Recording program that you have installed.
As for making a Bootable Copy of Windows 7 I have always downloaded the ISO Images from M$ and used Nero to copy the ISO and convert it to a Usable Format under Nero.
I haven't had any issues with either of these things in the past and they just work provided in the case of using a ISO Image you [b]Do Not[/b] just copy the ISO but convert it as you burn it to the Disc.
In the past I have used Easy CD Creator, Nero, Gear and never had a single problem though I have only ever needed to use Gear once but with both Easy CD Creator and Nero I have used these for many years without any problems.
