我最近在UEFI中安装了Ubuntu 15.04和Windows 10（我使用手动模式＆＃34;其他东西＆＃34;选项在磁盘的未分区区域手动创建分区）
当我启动PC时，grub无法启动，我会自动登录Windows。我试图通过USB在LiveCD上执行此操作：
deshack.net/ubuntu-dual-boot-grub-doesnt-start
然而，当我使用efibootmgr -v时，我得到以下输出：
ubuntu@ubuntu:~$ efibootmgr -v

我还尝试了bdcedit / set {bootmgr} path \ EFI \ ubuntu \ grubx64.efi并在Windows上关闭了Fast Startup。
如何在启动过程中自动启动grub？
