Windows 7 setup won't recognise any HDDs

[ruubl]

I'm trying to install Windows 7 and the setup isn't recognising any of my hard drives. I know they work because I've tested them on another computer. Odd thing is the BIOS just says 'Hard Drive' rather than listing the manufacturer and model like it usually does.

Any ideas why this might be happening?

Where did you get Win7? Did you burn the DVD or write to flash stick yourself? How?

Fill in your System Specs in bottom left corner of your post. Are these newer HD's with an older mobo?
