I have the same problem too.
I tried deleting my dstd file so i can repatch it, but then my 6470b won't boot.
Instead it is stuck on the boot screen. Any idea what's wrong with it?

What hardware is in your 6470b? CPU? Screen resolution?

To booting with flags as you did when installing: IGPEnabler=N GraphicsEnabler=N -x -v

Intel Core i5-3230M 2.6ghz
HD 4000 Graphics
8gb RAM
Screen resolution 1366x768

I will try using the correct bootflags and i will report back.
Thanks RehabMan
