You will need Windows to flash the BIOS. If you don't have an installation disk for Windows create one from ISO and burn to disk

You don't need to enter a licence key and can run for 30 days.Once you have flashed the BIOS per your manual you can use the installation disk to format the drive when you get to the 'Where do you want to install windows' screen and choose 'Drive Options(Advanced)'
