If I boot my computer from CD, is it still possible to use a CD drive to burn data to another blank CD?

When you start up with Active@ Boot Disk, Active@ Boot Disk boots entirely into the computer's memory (RAM), and runs entirely from memory. By doing this it enables you to insert a second optical device that contains drivers or software or can be used for CD/DVD/Blu-ray burning.

You can remove a CD/DVD/Blu-ray or Flash Drive after computer is started up and Active@ Boot Disk will continue working.
