How do I take the raid partition off

[Default-]

How do I take off a raid partition on my hard drive? I went to reinstall windows on my ssd 120 gb and this message came up......windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, windows can only be installed to GPT disks. I have a x99-a11 asus mother board but can’t seem to find out how to reverse the raid partition. Can anyone help me please?

Disconnect all other drives.
Start the install process
Delete ALL partitions, and reformat the remaining large partition. GPT.
Continue...

The message you're quoting does not mention RAID anywhere....
