My hard drive is already partitioned with a fat32 file system into one c drive. I want to format the drive and do a clean install of my operating system. Do i have to erase the partitions and logical drives, then re-partition and then format. or do i format the drive, then re-partition? do i use fdisk for this or is there a better way to do this? I've never done this before and am not sure of the steps.
