I tried to install the Windows 8 CP on my Lenovo W520 with no success as I posted about in the past.I was only able to install Windows 8 CP only if I disabled the Nvidia graphics card and just used the integrated Intel controller. This was of no real use as I need dual monitors.

With the release of Windows 8 RP I though I would try again.

The first attempt failed with the same problem, it hung detecting devices. I check the BIOS and noticed I was set to discrete only (the Nvidia setting). I knew the RP should work on the W520 as other at the office have got it working. So I changed the BIOS to Nvidia Optimus (the auto swap system between Intel and Nivdia) and tried again – and it worked. So this is the first post from Windows 8.

Now to find drivers for the other devices in the W520
