Windows' diskpart can be quite picky. I added the option to MakeInstall to prevent it from formatting the disk itself, and just use the partitioning as-is. This requires you format the disk using some other tool ahead of time though.

Per the main menu of MakeInstall, you'll want to include F in your command to have it skip formatting:

    F = Skip formatting the disk - will install the boot manager to the first
        partition, and dd the recovery image to the second.

In order to properly format the device ahead of time, you'll need 2 partitions. The first should be a 200 (or so) MB FAT32 partition, this is where the EFI will reside. The second needs to be a RAW partition of a size large enough to hold the HFS+ image for the recovery environment (usually 1GB or more). It is important that it is a RAW partition, as MakeInstall uses dd to write the contents of the BaseSystem.dmg to the partition - and Windows cannot natively read/write HFS+ - so it needs a blank canvas per se for that data.

thanks.However, I use DiskGenius software, but I cannot find the function of creating a raw partition in GPT mode. How can I create a raw partition? Should I use the diskpart tool that comes with the system? Or is there any other better software?

The diskpart that MakeInstall uses is the one that comes with the system. It just generates a script for that to run with the disk info filled out - and pipes it to diskpart via the /s switch. You might have luck using Disk Management - which acts like a GUI front-end to diskpart - but that may also encounter the same issues.

I'm not sure how to do the formatting in DiskGenius though, as it's not something I've ever used.
