我安装了 Windows 10，然后以双启动方式安装了 Ubuntu，但现在，当我启动 PC 时，我没有 Windows 10 选项，只有 Ubuntu。我尝试改变了很多东西。
- 我更新了 grub。
- 我尝试使用
sudo nano /etc/grub.d/40_custom它来编辑文件，但是 grub 无法识别我的操作。 - 我运行了 Boot-Repair 并得到了以下启动信息脚本：

你有什么想法？
我可以使用以下选项以安全模式访问 Windows：
menuentry "Windows UEFI bootmgfw.efi" { search --fs-uuid --no-floppy --set=root 327F-75AC chainloader (${root})/EFI/Microsoft/Boot/bootmgfw.efi }
menuentry "Windows Boot UEFI loader" { search --fs-uuid --no-floppy --set=root 327F-75AC chainloader (${root})/EFI/Boot/bkpbootx64.efi }
但除了安全模式之外，它无法通过其他方式进入。
答案1
Windows 10 始终仅在安全模式. 按⊞ Win+ R-> 输入msconfig-> 点击好的按钮 ->引导标签 -> 取消选中安全启动-> 点击申请按钮 -> 点击好的按钮。
