Bios doesn't see HDD

[ReefGoudswaard]

So today my friend and I have built a pc for him. Everything went fine, until we started up the pc and tried to install Windows 10. (also only the case fans weren't spinning, but that is another story.) When we were asked on which drive we wanted to install windows nothing showed up. I went to the bios and there it also said nothing was connected. I tried different sata data cables, power cables and even a different HDD on its own, but again same story. I also tried updating the bios, but again it didn't show up. I am scared either something is broken or that i have overlooked something very simple in the building process, like for example connecting a certain cable. Can anyone help me fix it?

CPU: G4560
GPU: RX 480
MOBO: MSI B250 Krait Gaming motherboard
Storage: Western Digital Blue 1TB
RAM: 8GB Crucial Ballistix Sport
PSU: Seasonic S12II-Bronze 520W
Case:  NZXT S340

 

If someone needs further information, just ask!

seems unlikely that SATA would be disabled, but have you checked that in the BIOS ? i have SATA disabled on my work rig for example cos i just boot from PCIe. 

 

Try CMOS reset ?

I tried looking for it, but I couldn't find it. I did however find something called sata hot plug, not sure if that would make a difference.

As for the CMOS reset, I am quite careful with it, since last time (in a different PC) when i removed the battery and then put it back in the computer stopped booting entirely, so I might try that later
