I would like to restore factory setting or wipe the laptop completely clean before getting rid of it.

I have a Dell Inspiron 9300 with Windows XP.

I have tried F* as it is starting to get to the Advanced Boot Options.  But then there is no "Repair Your Computer" as suggested by other online info.  Lots of choices, but not that one.

I have tried Ctrl-F11, many,, many times and in several different ways and it does nothing.

Anyone  know how to do this?
