在双启动计算机上，我突然无法启动到 Windows 10，并且 grub 加载程序不再加载。我重新安装了 Linux Mint 19.3 Tricia。现在我正在尝试将 Windows 添加到位于 sda1 上的 grub。
当我运行 os-prober 时，我得到以下信息，我认为这意味着它看到了 Windows。
$ sudo os-prober
/dev/sda1:Windows 10:Windows:chain
但是当我尝试更新 grub 时，它说看不到 sda。 update-grub 永远运行。
fdisk 说分区不在物理扇区边界上启动。

Partition 1 does not start on physical sector boundary.
Partition 3 does not start on physical sector boundary.
我尝试运行 ntfsfix
$ sudo ntfsfix /dev/sda1
Mounting volume... OK
Processing of $MFT and $MFTMirr completed successfully.
Checking the alternate boot sector... FAILED

任何帮助将非常感激。
update-grub 的作用如下：
$sudo update-grub
