A message appears stating, The disc inserted is a re-writable disc. Insert a CD-R when you attempt to create your recovery media. If you attempt to use a DVD-RW disc, the message will prompt you to use a DVD-R instead.
You can only create recovery media once. HP requires the use of R media instead of RW to avoid the possibility of accidentally erasing a recovery disc later. Use a CD-R or DVD-R disc to create the recovery media.
