Computer won't boot from SSD

[Thomas_Wafer6]

So I bought a new 240GB SSD the other day and just got around to installing it. The problem is that when I try to install Windows it says that the bios doesn't support the media device and to change the CSM (compatibility support module). I have found the setting but have no idea what it's talking about. Can someone please help? My motherboard is the Asus H81M Plus

You have to enable CSM.
There should be 3 options [Auto, Enabled, Disabled]

It's enabled by default

Just clean the drive with diskpart before installing windows onto it.
Diskpart is accessible from command prompt, when you boot from windows installation media.

• diskpart
  list disk
  select disk x (x - number of your ssd)
  clean
  exit
