So here's a cool OSD Function ... if you happen to have PowerShell added to WinSE, and the OSD Module, you can easily partition your drive ... the right way
You'll start by holding down left Shift + F10 to open a Command Prompt, then enter PowerShell. Once PowerShell is started, you can use New-OSDDisk without any parameters for Information Mode
