Reboot and insert proper media boot device: Dell Vostro 430

[KvackEvolution]

Hi!

I have an Dell Vostro 430 desktop PC that dosn't want to boot Windows 7.

The thing is that when i boot it up and either press "F12" for boot menu or wait the POST out it comes to this screen with a list of all the SATA ports on the motherboard (which is 4). The harddrive is installed on port 1 and the optical drive on port 3, which is prompted on the screen that looks like this:

Reboot and Select proper Boot device or Insert Boot Media in selected boot device and press a key
SATA 1: Installed
SATA 2: None
SATA 3: Installed
SATA 4: None




But in BIOS neither of those are auto detected(picture below). Boot mode is set to AHCI. I have tried set it to ATA but nothing changes. I have even tried clearing CMOS, but nothing changed either.

The harddrive works fine though if i plug it in to another PC, even tired the og sata coord from the Vostro works without a doubt.

How can i fix this so that the PC can boot Windows again ? Is the BIOS bricked ?

Specs:

Power supply problem?

Don't think that it is the PSU since i used it for powering the drive on the other PC meanwhile it was still connected to the Dell Motherboard.

And i could still eject the optical drive.

I will not boot anything. Tried making a bootable Dell DDDP usb just to reflash the BIOS. The thing is that if you promp it at post to go to Boot menu by pressing F12, it just skips it and try booting anyway. I have no boot priority of devices in BIOS either.
