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

Any personal computer can boot from external devices other than the built-in hard drive.

With Active@ Boot Disk you may start your PC from CD/DVD, USB Flash drive instead of a hard drive.

Hoe to start your PC from CD/DVD or USB Flash drive do the following?

  1. Create Active@ Boot Disk (Bootable CD/DVD or Flash drive)
  2. Insert it into PC and restart/reboot.
  3. If Active@ Boot Disk doesn't start, change the BIOS boot order so that CD or DVD or USB Flash drive is listed first.

Most of computer systems has a CD booting priority by default. Starting from USB flash drive always requires changing boot priority sequence.
