2. Insert the Restore DVD in the drive and reboot the device. When the BIOS message
Press <F2> to enter Setup or <ESC> to show Boot menu
appears, press the F2 key.
3. Select the Boot menu and move the entry "DVD Drive" to the first position.
4. Close the BIOS setup with the "Save Changes & Exit" option.
5. Follow the on-screen instructions.
Caution
All existing data, programs, user settings, authorizations or license -keys on the drives will
be deleted and are therefore lost.

Note
The "Legacy USB Support" option has to be set to "Enabled" in the Advanced menu of the
BIOS so that the device can address a USB DVD-ROM drive.
