推荐答案

此答案适用于那些使用UEFI且在删除grub之前已删除Ubuntu分区的人

您将在Windows 10中执行此操作.不需要可启动媒体.

You will be doing this from Windows 10. No bootable media required.

在bootrec /fixmbr，bootsect /nt60和带有boot-repair建议的Ubuntu失败的地方，这对我有用:

Where bootrec /fixmbr, bootsect /nt60 and the Ubuntu live with the boot-repair suggestions have failed, this has worked for me:

(此答案从

以管理员权限运行cmd.exe进程

运行diskpart

键入:list disk然后是sel disk X，其中X是启动文件所在的驱动器

键入list vol以查看磁盘上的所有分区(卷)

通过键入以下内容来选择EFI卷:sel vol Y其中Y是SYSTEM卷(这几乎总是EFI分区)

为方便起见，请键入以下内容来分配驱动器号:assign letter=Z:其中Z是一个空闲(未使用)驱动器号

键入exit保留磁盘部分

仍然在cmd提示符下，键入:Z:并按Enter键，其中Z是您刚创建的驱动器号.

键入dir列出此已挂载EFI分区上的目录

如果在正确的位置，应该会看到一个名为EFI

的目录.

键入cd EFI，然后键入dir，以列出EFI

中的子目录.

键入rmdir /S ubuntu删除ubuntu引导目录

1. Run a cmd.exe process with administrator privileges
2. Run diskpart
3. Type: list disk then sel disk X where X is the drive your boot files reside on
4. Type list vol to see all partitions (volumes) on the disk
5. Select the EFI volume by typing: sel vol Y where Y is the SYSTEM volume (this is almost always the EFI partition)
6. For convenience, assign a drive letter by typing: assign letter=Z: where Z is a free (unused) drive letter
7. Type exit to leave disk part
8. While still in the cmd prompt, type: Z: and hit enter, where Z was the drive letter you just created.
9. Type dir to list directories on this mounted EFI partition
10. If you are in the right place, you should see a directory called EFI
11. Type cd EFI and then dir to list the child directories inside EFI
12. Type rmdir /S ubuntu to delete the ubuntu boot directory

假设您只有两个操作系统(Win 10和Ubuntu)，您现在应该能够直接启动到Windows，而不会出现黑屏.

Assuming you only ever had two operating systems (Win 10 & Ubuntu) you should now be able to boot directly to Windows without hitting the black grub screen.
