grub-probe：警告：磁盘不存在，因此回退到分区设备 /dev/sda1

Question

我试图让 GRUB 启动 Windows，但遇到了问题。每当我尝试运行时grub-probe --target=fs_uuid /mnt/bootmgr，我都会得到以下信息：

grub-probe: warning: disk does not exist, so falling back to partition device /dev/sda1.
grub-probe: warning: disk does not exist, so falling back to partition device /dev/sda1.
grub-probe: warning: disk does not exist, so falling back to partition device /dev/sda1.
grub-probe: error: disk `hostdisk//dev/sda1' not found.

/dev/sda1绝对存在。为什么会这样？

Answer 1

错误消息具有误导性。磁盘存在，您只是无权访问它们。尝试使用sudo.
