Was having some problems with my computer, a Dell XPS 8700, 1T HD 16 Ram .i7,Tried to reset to factory, got this message, "Unable to reset PC. A required partition is missing." Any help appreciated.
You must have messed around with your computer enough that you deleted the partition with the reset information on it. Contact Dell.
I agree with grandpa, anytime you re-format a disk with a hidden restore partition you can wipe it out.... sad, but true!
