完成步骤后报错0xc0000225，网上搜索的原因一般说是BCD文件错误

请问如何解决？

Error 0xc0000225 on laptop with windows 8.1, how to repair without a recovery disk?

0xc0000225: Fix for Windows 7, 8, 8.1

然而这些解决方案似乎都需要windows下的一些东西...而我现在只有ubuntu

如果可以登入 Ubuntu 桌面
把下面指令 複製 貼進終端機 執行
sudo /etc/grub.d/30_os-prober
把結果直接 選取/複製/貼上來
目的 希望把 windows 開機選項 加入 Ubuntu 的 grub 2 開機選單

如果無法登入 Ubuntu 請再貼文

以上指令执行后没有反应。

我再详细描述一下我的情况：ubuntu系统正常，能进入grub2编辑界面，也能在进入系统后修改/etc/default/grub.cfg 为grub2界面加入windows的选项。
但是，boot之后报错0xc0000225

另外，尝试了boot-repair的一般性修复，不起作用

把下面指令 複製 貼進終端機 執行
sudo fdisk -l
把結果直接 選取/複製 貼上來

1. 把下面指令 複製 貼進終端機 執行
1-1. sudo mount -t ntfs-3g /dev/sdb3 defaults,locale=zh_CN.utf8 /mnt
1-2. sudo ls -al /mnt
把 1-2. 的結果複製貼上來

第一个的结果

Usage:
mount [-lhV]
mount -a [options]
mount [options] [--source] <source> | [--target] <directory>
mount [options] <source> <directory>
mount <operation> <mountpoint> [<target>]

Mount a filesystem.

Options:
-a, --all mount all filesystems mentioned in fstab
-c, --no-canonicalize don't canonicalize paths
-f, --fake dry run; skip the mount(2) syscall
-F, --fork fork off for each device (use with -a)
-T, --fstab <path> alternative file to /etc/fstab
-h, --help display this help text and exit
-i, --internal-only don't call the mount.<type> helpers
-l, --show-labels lists all mounts with LABELs
-n, --no-mtab don't write to /etc/mtab
-o, --options <list> comma-separated list of mount options
-O, --test-opts <list> limit the set of filesystems (use with -a)
-r, --read-only mount the filesystem read-only (same as -o ro)
-t, --types <list> limit the set of filesystem types
--source <src> explicitly specifies source (path, label, uuid)
--target <target> explicitly specifies mountpoint
-v, --verbose say what is being done
-V, --version display version information and exit
-w, --rw, --read-write mount the filesystem read-write (default)

-h, --help display this help and exit
-V, --version output version information and exit

Source:
-L, --label <label> synonym for LABEL=<label>
-U, --uuid <uuid> synonym for UUID=<uuid>
LABEL=<label> specifies device by filesystem label
UUID=<uuid> specifies device by filesystem UUID
PARTLABEL=<label> specifies device by partition label
PARTUUID=<uuid> specifies device by partition UUID
<device> specifies device by path
<directory> mountpoint for bind mounts (see --bind/rbind)
<file> regular file for loopdev setup

Operations:
-B, --bind mount a subtree somewhere else (same as -o bind)
-M, --move move a subtree to some other place
-R, --rbind mount a subtree and all submounts somewhere else
--make-shared mark a subtree as shared
--make-slave mark a subtree as slave
--make-private mark a subtree as private
--make-unbindable mark a subtree as unbindable
--make-rshared recursively mark a whole subtree as shared
--make-rslave recursively mark a whole subtree as slave
--make-rprivate recursively mark a whole subtree as private
--make-runbindable recursively mark a whole subtree as unbindable

For more details see mount(8).

第二个的结果

1. 抱歉
疏忽了
試試
sudo mount -t ntfs /dev/sdb3 defaults,locale=zh_CN.utf8 /mnt

2. 補充
sudo mount -t ntfs-3g /dev/sdb3 defaults,locale=zh_CN.utf8 /mnt
是早期的寫法

3. 如果你第一個失敗
這個可能不正確

依旧返回相同的结果

再試試
sudo apt-get install ntfs-3g
sudo umount /dev/sdb3
sudo mount -t ntfs /dev/sdb3 /mnt

如果還是錯誤 請提供你的 windows 版本

现在 mount 指令没有返回
sudo ls -al /mnt 返回

你已經完成安裝 Windows 並且可以開機進入 Windows 了嗎 ?

并没有，在 grub2 编辑界面打下 boot 敲回车后就出现报错
