brant999 :
It was an empty hard drive and I installed windows 8 on it so I guess how do I format the whole disk?
OK
Boot from your install media
When it gets to 'where to install', select Advanced
Select each partition, Delete
Eventually you will be left with one large unallocated space. From your previous info, I'm guessing 2TB?
Now...we get to determine if we want to partition that drive. Personally, I wouldn't...but if you want to, do it.
Since you apparently have a 2TB drive, create a partition of no less than 100GB.
Install Windows in that partition.
Figure out the rest later.
