How do I setup RAID 5 for Windows 7?

I tried it before without success. Is there third -party software or something that's required?

When I try to click on RAID 5:

    @Liron_b Software Raid-5 is not supported in Windows 7 - You will need Windows Server in order to use a Software Raid-5 like you are trying to do - If you want to Raid-5, you will have to boot into your Raid Controller, either on-board or externally installed, and setup Raid-5 that way - However, I believe you will have to wipe your machine in order to setup a Raid-5 from scratch, and you will need all identical drives for it to work – Mike Diglio Oct 25 '15 at 23:19

    @Liron_b There are 2 different types of Raid'ing - Software and Hardware - Software Raid is when you use the Operating System to setup a Raid and have it controlled by Disk Management - Hardware Raid is when you use a Raid Controller, either PCI-E or on-board from your Motherboard - The Raid Controller will manage your raid and this is the only way, when on Windows 7, to setup a Raid 5 - You will have to lookup your model Motherboard to see if it supports Raiding, and if it does, you will have to boot into it and setup Raid-5, along with adjusting your BIOS settings – Mike Diglio Oct 25 '15 at 23:32

Windows 7 does not support creating a software-based RAID5.

The option is visible (although not selectable) because the same drive management console utility is used in Windows Server as well, which does support creating a software RAID5.

See this other SU question for more info:

Which software raid modes does each version of Windows 7 support?

To accomplish RAID5 with Windows 7 you will need a hardware (or firmware) based RAID controller that supports RAID5; one which supplies drivers compatible with Windows 7.
