我无法修复我的双启动设置（第一个驱动器上安装 Windows，第二个驱动器上安装 Kubuntu）。我之前在第二个驱动器上安装了 Manjaro，而 Kubuntu 的安装（覆盖 Manjaro）可能搞乱了启动过程。现在 Kubuntu 已安装，但不幸的是我无法启动 Kubuntu。使用启动修复 (https://help.ubuntu.com/community/Boot-Repair) 工具未能修复此问题。
任何帮助将不胜感激。
谢谢

Adding boot menu entry for UEFI Firmware Settings
Boot successfully repaired.
You can now reboot your computer.
Please do not forget to make your UEFI firmware boot on the Ubuntu 20.04.4 LTS entry (sda2/efi/ubuntu/grubx64.efi file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.
If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi
