still waiting for root device - dual boot issue?

[yoyoman]

I have a asus ul30vt-x1k with dual video cards. When I boot with sata bios set to 'enhanced', I can boot properly. However, when I switch to 'compatible', I get the root device error. I've read several success stories for getting the 210m card to work when switching the bios to compatible, so I'm curious why I'm having problems.

I am trying a dual boot setup right now. Is it possible that this is causing the problem? I'd hate to lose my Windows installation since one of this laptop's greatest assets is the 10 hour battery life, which I will only see while using Windows.

As a test, I installed to a 3rd partition I had, and I was magically able to boot with that install using the 210m. I don't know what the magic juju was, but it's working now. I was also able to restore that drive onto the first one and boot, so it's definitely not a dual boot issue.

YAY!
