Hi gogregerson, the Recovery Partition does not
need or require a drive letter. It has been left off so Windows won't try writing to it and damaging it. Remove the drive letter.
When you are booting up, on the POST screen there should be a list of keys to press for options. Using F8 gets you into the Windows repair options, not Dell's. Usually for a Dell you press F11 or F10 to access the recovery area. This will also reinstall all factory bloatware.
A better option which has been used successfully is Reinstalling Windows 7
. Save all of your personal data to some external device first.
