Setting up a Lenovo Thinkpad Carbon X1 and one of the first things I’m doing is basically reinstalling everything clean from scratch. The first thing I did was go into the Lenovo Solution Center -> Restore Media which had the option to copy the System Restore partition to a USB drive.
With that out of the way the next thing was to boot off a Knoppix USB key to the command line (enter 2 at the prompt) and then run gdisk.
In gdisk I used the almost the entire disk for the new Windows 8 partition which is set to type 0700.
However Intel Rapid Start Technology requires its own small partition which must be equal to or larger than the RAM size. Because of cylinder boundary issues you may not always be able to create an exact-size partition with gdisk. I was shooting for a 7GB partition for the this which is what it was with the factory setup, but I ended up with 6.5 GB which is totally ok.
Now the odd, tricky thing about the Rapid Start partition is that the type has to be set to:
D3BFE2DE-3DAF-11DF-BA40-E3A556D89593
No, you are not hallucinating. That is what you have to enter when it asks for the partition type.
Oops. Now in Windows 8 setup and it refused to install on the above-created partition, complaining that it was because it is a GPT. What? So I just deleted everything and created a new one, leaving 7 GB off the size for the Rapid Start partition. This then also created a 320MB System Reserved partition.
Its installing now so hopefully everything will be ok. I will have to boot into Knoppix again later and set the partition type again for the Rapid Start partition.
