The Create Factory Default Backup dialogue box opens.
This dialogue box tells you the number of blank, recordable discs you will need
to complete the recovery discs. Make sure that you have the required number
of identical, blank discs ready before continuing.
3 Insert a blank disc into the drive indicated in the Backup to list, then click
Next. You will be shown the backup progress on the screen.
The drive ejects each disc as it completes burning it.
4 Remove the disc from the drive and mark it with a permanent marker.
Important: Write a unique, descriptive label on each disc, such as
'Windows Recovery Disc 1 of 2' or 'Apps/Drivers Recovery disc'.
Make sure you keep the discs in a safe place that you will
remember.
5 If multiple discs are required, insert a new disc when prompted, then click
OK. Continue recording discs until the process is complete.
