我已经安装了 RHEL 7.2 和 Windows 10。Windows 10 已经安装，然后 RHEL 安装正确并且工作正常。我现在已经配置了40_custom文件 Windows 选项在启动时显示，但在选择 Windows 10 时它显示错误：
An operating system was not found. Try disconnecting any drive that don't contain an operating system.
我的/etc/grub/40_custom文件条目如下
menuentry "windows 10" --class windows --class os {
insmod part_msdos
insmod ntfs
set root='(hd0,msdos1)'
search --no-floppy --fs-uuid --set=root B4FC1483FC1441D2
chainloader +1
}
我的blkid命令显示详细信息如下

答案1
您似乎以某种方式使用旧版启动来启动并安装 RHEL。这是行不通的，因为您现有的操作系统使用 UEFI 启动；您需要重新安装使用 UEFI 引导的 RHEL。
