Question Help, how do i fix this?

[EschatonRage]

The motherboard M.2 slot #1 shares bandwidth with a SATA 6.0 Gb/s port. When the M.2 slot is populated, one SATA 6.0 Gb/s port is disabled.

The motherboard M.2 slot #3 shares bandwidth with SATA 6.0 Gb/s ports. When the M.2 slot is populated, two SATA 6.0 Gb/s ports are disabled.

Is there something wrong with the hdd or the sata on the motherboard? How do I fix this? I don't know which is disabled and which one isn't.

Here is my build:

And also got this when I try to boot the pc: Reboot and select a proper Boot Device or Insert Boot Media in selected Boot device <<< What does that mean?

Nothing wrong, that's how it works in that and many other Intel MBs.
"Reboot and select a proper Boot Device or Insert Boot Media in selected Boot device" means there's no valid OS installed.

If this is a new build you should be installing a clean windows 10, using wither a USB or DVD. If you've used an existing HDD with windows already installed this could lead to problems, the lines you see above denote that you might have the SSD in M.2 #1 and that'll disable SATA #6 (I'm not sure you need to check the MOBO manual) and you have the HDD plugged into SATA #6.
