无法从 MBR 中删除 GPT 数据

我很难让 Ubuntu 安装程序（和 gparted）识别我的 MBR 类型磁盘上的分区。其他操作系统和磁盘工具可以很好地读取磁盘结构和其中的文件。我已使用 fixparts 写入新的 MBR，但问题仍然存在。我假设问题源于磁盘上仍然存在的保护性 MBR 数据，但我不知道如何在保留 NTFS 数据分区的同时删除它。

从 3 加载 MBR 数据：

警告：0xEE 分区不是从扇区 1 开始的。这可能会在某些操作系统中造成问题。

MBR 命令（？获取帮助）：

运行 gdisk 显示

Found invalid GPT and valid MBR; converting MBR to GPT format in memory. THIS OPERATION IS POTENTIALLY DESTRUCTIVE! Exit by typing 'q' if you don't want to convert your MBR partitions to GPT format!

Most versions of Windows cannot boot from a GPT disk, and most varieties prior to Vista cannot read GPT disks. Therefore, you should exit now unless you understand the implications of converting MBR to GPT or creating a new GPT disk layout!

看起来 gdisk zap 命令或 MBR 重建处理了有问题的 GPT 数据，但直到重启后才生效。
