最近几天在研究安装黑苹果，要安装 macOS Catalina 系统。
这就涉及到了搭建 opencore 会恢复 U 盘，但是到了 gibMacOS 软件的 MakeInstall 制作恢复 U 盘的时候，出现错误。在 github 咨询软件开发者，他回复道：
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.

我问题来了，第一个 200MB 分区很容易创建，但是使用 diskgenius 却找不到如何创建“RAW 分区”选项，大家是如何创建这种分区呢？
