How to make Vista recognize HDD?

[ryberg]

Hi,
Currently trying to install an OS on my first homebuilt PC. Now for the last few hours I've been trying to install Vista on it, and everything (which really isn't a lot) goes smoothly till I get to the screen where I have to choose what drive to install Windows at. Here I'm met by a blank screen and the message: "No drives were found. Click Load Driver to provide a mass storage driver for installation."
So I tried the DVD that followed the motherboard, I downloaded the necessary drivers for my harddisc and placed them at a USB stick and a CD. Now when I browse either of them and locate the drivers they do show up, as functional for my machine, but during the install of the drivers I'm met by another error-message: "To continue installation, use the Load Driver option to install 32-bit and signed 64-bit drivers. Installing an unsigned 64-bit device driver is not supported and might result in an unusable Windows installation." where after I'm back to the browsing menu.
Is anyone cabeable of helping me out of this mess?

Is the drive showing up in your BIOS?
Do you have the SATA ports enabled the drive is connect to?

The drive is showing up correctly in BIOS. As to the other part, I'm not sure how to determine that - Is that a BIOS setting too?
