Are you using XP as the OS or Vista ?
If you have XP the CTRL + F11 is what works
Do you see a blue banner with www.dell.com on it just
after the Big Dell logo goes away you hole CTRL and tap F11 .
If you have Vista you tap F8 at boot!
If you have changed the mater boot record by dual booting
or installed XP from the CD or have formatted the drive
the CTRL + F11 will not work anymore you will have to use the CD to install XP .

factory restore option !
What about for Windows 7? I have the Dimension E520 desktop and CTRL F11 doesn't work and when I hit F8 it does not give me an option to do a factory reset. Just a System Restore which doesn't help me because I don't have any restore points.
The PC Restore feature is only found on factory delivered operating systems. The most recent operating system delivered with the Dimension E520 is Vista; if you still had that operating system, you would have found "Repair My Computer" in the F8 menu.
If you did not make a system image with something like Acronis True Image, or EASUS, or Ghost, I'm afraid the only way you will restore your computer is to install everything from external media. You might be able to repair your Windows installation using the Windows 7 installation DVD if you do not wish to erase everything and start over.
