我尝试在 Ubuntu 18.04 之后安装 Windows 10这个帖子，进入 Live CD 后，运行
sudo fdisk -l
就像这样后续帖子- 表示这是输出

这似乎有太多的分区，但我知道 Ubuntu 在磁盘中1 TB，而 Windows 也在磁盘中，140GB所以
我这样做了
sudo mount /dev/nvme0n1p3 /mnt
ls /mnt
确实看到了我的 Ubuntu 文件，但运行后
for i in /dev /dev/pts /proc /sys; do sudo mount -B $i /mnt$i; done
sudo chroot /mnt #change the root
sudo update-grub # now update grub
我有这个输出

我无法启动 Ubuntu 和 Windows
编辑：
其他发布的解决方案不起作用，因为我认为有些东西损坏了，感觉好像磁盘太多了，因为我只使用了 2 个磁盘，而 2TB 是全新的，没有被触碰过。因为我可能选择了错误的磁盘分区来启动？我正在连接 GParted 中的所有不同磁盘：
