So run Ubuntu from a flash drive and then save my files on to something (I have an external hd) and then reinstall windows as you say?
You probably have a corrupt filesystem which can sometimes be repaired, but it's best to start a new. If windows however, won't even install than you most likely have a dead drive and need to get a new one. Either way try and run Ubuntu and save your data if the HDD has so much life left in it.
