Hi I have an Asusx550c laptop and it came preinstalled with windows 8 and everything else that comes with a new laptop this is all on the C drive and on the D drive there is nothing the trouble is all the things that I have put on the pc are also on the C drive and I cannot restore to factory settings because there is no partition is there a way to partition the section of C drive where the preinstalled set-up is so I can wipe the rest? Hope you can help thanks
