Lenovo seems pretty unique and adding ugly hacks to their hardware (like disabling ACHI), and then changing the PCI ID of a "fake raid" chip. So not only does this break linux, but it also breaks the standard release of windows.

So even if you want to install MS Windows from official microsoft media, you can't.

Why would lenovo would disable AHCI (which breaks windows and linux), then mess with a fake RAID (despite having a single storage device).

Seems like Lenovo REALLY doesn't want consumers reinstalling the OS.... makes one wonder.
