我在 Windows10 旁边安装了 Kali。我决定卸载 Kali，因此删除了分区并使用 EasyBCD 恢复到 Windows MBR。启动时 Grub 救援仍会加载。因此我运行了一个实时 Ubuntu 并运行了启动修复，但也没有删除 Grub 救援。我想知道我是否有其他选择可以尝试删除 Grub 救援，或者指南链接会很方便。我帖子的底部有启动修复报告
Windows 以 EUFI 启动，我可以将其切换为安全模式，然后直接启动到 Windows。但我更想知道如何在没有 Grub 救援的情况下获得干净的 MBR

答案1
显然，您的 Windows 是 UEFI 安装，但您为 CSM（“传统启动”）安装了 Kali/grub。
尝试擦除保护 MBR 并让 gdisk 为您写入一个新的：
dd if=/dev/zero of=/dev/sda count=1
gdisk /dev/sda
w
确保不要错过，count=1因为如果错过了，dd将会擦除您的整个驱动器。
