I have a Latitude D620 that I need to restore to factory. Everything I've read says to power the unit off and then back on and press and hold F8 to bring up the advanced boot menu and then go to "repair my computer" to start the process. Only problem is that when I press F8 that option isn't available. what comes up is the "windows advanced options menu" and the only options that are available are as follows:

Safe mode

SM w/ networking

SM w/ command prompt

Enable boot logging

Enable VGA mode

Last known good config.

Directory services restore mode

Debugging mode

Disable auto restart on sys failure

Start windows normally

Reboot Return to OS choices menu

and thats it. Am I doing something wrong. Everything I read has the exact same process. Any help would be apprecieated.
