Can't install windows on my Hard Drive

[FrederikKlit]

Yesterday, I build my new gaming rig:
Asus Z87-K
i5-4670k 3.4 GHz
Vengeance 8 GB 1600 MHz
GTX 660 oc
Corsair CX600M
Hyper 212 EVO
and at last WD 1TB Caviar blue.

Now, when i'm about to pick a hard drive to install my windows (right now, the only operative system i have is windows vista ultimate 64-bit, i don't have money to buy another windows right now) it says it can't install it because the SATA drive isn't ntfs. I don't now what to do.. Please help!

Delete the partition. A window will open asking where you would like to install Windows. In order to perform a clean install, you need to delete the old partition and start with a clean slate. Click “Drive options (advanced).” This will give you the ability to delete and create partitions.
Select the partition of your existing operating system and click the Delete button.
If you are installing an operating system for the first time on this hard drive, then there will be no partitions to delete.
If your hard drive has multiple partitions, be sure to delete the correct one. Any data on a deleted partition is lost for good.
Confirm the deletion process.

That's the problem. This Hard Drive is new so there shouldn't be any partition and therefore no problem?
