I was attempting to replace a version of windows 8.1 that was reported here that it had been hacked. By a friend, I was told to do a clean install after I had repartitioned it and formated to clear all the hacks off. I understood windows 8 could handle this. I went into install. I tried to break down the non reserve area (1TB) into 3 areas, but it would not let me, I understtod it wanted the allocated space removed, so I did. When I tried to re-allocate a portion it gave me an error due to file status in the reserve area, and as i understood it to say it needed reformating in that area. It offered to reformat it and I allowed. Now the install disk claims after it reformated the reserve area is not formated correctly for system files so it will not procede. I see no area to tell it how to format correctly so without being able to boot that system, how can I correct this to the proper format and then partition it into 3 areas? I have access on another system to post this and down load something if told to.
