Bug#293683: My problem!
So I got the rc2 build of the installer and didn't install usb and it worked. then got the updates and new kernel made it.
When I had screwd up for 3 times I got it, the appen kernel image name isn't working. So kernel is new now and all is good for me. But for others with nforce2 and downloading unstable installer i suggest to put the usb of from bios. install, new kernel, usb on from bios when booting to new kernel.
