The key to successfully recovering computers after a disaster is to carefully and properly prepare those computers for a disaster.
Consider what type of Windows computer is being protected, the available hardware, and the system BIOS when selecting the type of bootable media to create. You can also combine media to make updating the *.dr files easier. If you are using bootable CD-R or CD-RW, or tape, you can still back up the *.dr files to any location using the IDR Preparation Wizard so that you can easily update them when required.
Use the following table to decide which type of media to use.
