If this does not work, however, you can request Dell to send you replacement recovery disks for your model of computer by going *here* Just keep in mind Dell may charge for the disks, so if you do need to order them, be prepared to pay a minor fee, by using a credit card on their secured website. When the Dell logo appears, try pressing Ctrl-F11 or Alt-F11 at this screen, and if your system has the recovery partition, it should boot to it, and give you instructions on how to restore your system using this method. Shut down the computer completely, and restart it with the power button.
You can attempt to recover the system using the built-in recovery partition (if your system has one). SOURCE: hi, I have lost the recovery cd for my dell inspiron 710 m
