Dell Optiplex 9020 and Clean Installation of Windows 8.1/Windows 7

Hello All,

I have recently Order Dell Optiplex 9020 with Ubuntu.

Now I want to clean install Windows 8.1.  I know that this is possible on desktop but as Ubuntu already installed How I clean Install Windows 8.1. 

Do I need to set any thing for this into BIOS ?

If I clean Ubuntu does it cause any issue ? 

Please provide your suggestion and steps for this.

Follow my Windows Reinstallation Guide/A Clean Install of Windows:

You may securely wipe the drive with Ubuntu before Windows installation:

A Windows 8.1 bootable USB will install in SecureBoot/UEFI.

It means If I have bootable DVD for Windows 8.1 or Windows 7.

I insert into Drive and boot from that drive and install.

Is this work ?
