Intel RST
You've got a single SSD/HDD set up in RAID mode, and the Ubuntu installer won't recognize your SSD/HDD until you switch your disk setting in the BIOS from RAID to AHCI.
Making that switch comes with some problems though, as Windows will no longer boot.
You don't need to reinstall Windows...
Make sure to have a backup of your important Windows files!

- Right-click the Windows Start Menu. Choose
Command Prompt (Admin).
- If you don’t see
Command Prompt listed, it’s because you have already been updated to a later version of Windows. If so, use this method instead to get to the Command Prompt:
- Click the Start Button and type
cmd
- Right-click the result and select
Run as administrator
- Type this command and press ENTER:
bcdedit /set {current} safeboot minimal
- If this command does not work for you, try
bcdedit /set safeboot minimal
- Restart the computer and enter BIOS Setup (the key to press varies between systems).
- Change the SATA Operation mode to AHCI from either IDE or RAID (again, the language varies).
- Save changes and exit Setup and Windows will automatically boot to Safe Mode.
- Right-click the Windows Start Menu once more. Choose
Command Prompt (Admin)
- Type this command and press ENTER:
bcdedit /deletevalue {current} safeboot
- If you had to try the alternate command above, you will likely need to do so here also:
bcdedit /deletevalue safeboot
- Reboot once more and Windows will automatically start with AHCI drivers enabled.
