OpenCore 从0.7.2版本开始之后就放弃支持低于macOS Big Sur 11版本系统分区识别，OpenCore团队修改了 APFS 驱动的 MinDate 和 MinVersion 默认值，这个可以在发行文档 Differences.pdf 里查看：

MinDate

Description: Minimal allowed APFS driver date.

The APFS driver date connects the APFS driver with the calendar release date. Apple ultimately drops support for older macOS releases and APFS drivers from such releases may contain vulnerabilities that can be used to compromise a computer if such drivers are used after support ends. This option permits restricting APFS drivers to current macOS versions.

0 — require the default supported release date of APFS in OpenCore. The default release date will increase with time and thus this setting is recommended. Currently set to 2018/06/21 2021/01/01.
-1 — permit any release date to load (strongly discouraged).
Other — use custom minimal APFS release date, e.g. 20200401 for 2020/04/01.
MinVersion

Description: Minimal allowed APFS driver version.

The APFS driver version connects the APFS driver with the macOS release. Apple ultimately drops support for older macOS releases and APFS drivers from such releases may contain vulnerabilities that can be used to compromise a computer if such drivers are used after support ends. This option permits restricting APFS drivers to current macOS versions.

0 — require the default supported version of APFS in OpenCore. The default version will increase with time and thus this setting is recommended. Currently set to the latest point release from High Sierra from App Store (allow macOS Big Sur and newer(748077008000000 1600000000000000).
-1 — permit any version to load (strongly discouraged).
Other — use custom minimal APFS version, e.g. 1412101001000000 from macOS Catalina 10.15.4.

也就是说高于OpenCore 0.7.2 版本之后的OC引导只能看到10.13、10.14、10.15等安装U盘，但是等你安装到硬盘重启之后是无法看到分区的，解决这个方法也很简单，只要修改 MinDate 和 MinVersion 默认值就可以了。

解决方法

使用OpenCore Configurator软件打开你的config.plist文件；

把UEFI — APFS — MinDate 值改为 -1，UEFI — APFS — MinVersion 值改为 -1

然后保存config.plist文件，重启之后就看到分区了。
