Hi there cynicoren,
I would agree with USAFRet. Windows install should see it.
In case it doesn't, you can format it through the command line.
- Once you are in Windows setup, press shift+F10 to bring up the command line.
- diskpart [enter]
- list disk [enter]
- select drive [number] [enter]
- create partition primary [enter]
- select partition 1 [enter]
- active [enter]
- format fs=ntfs [enter]
- assign [enter]
- exit [enter]
- exit [enter]
Hope this will help,
