我在 SSD 上安装了 Windows 10 和 Ubuntu 20.04，但无法启动 Ubuntu 20.04。它总是启动 Windows。我运行了 Boot-Repair，但没有用。http://paste.ubuntu.com/p/WvMfFgJvXN/这是我的启动修复摘要。

SFS detected. You may want to retry after converting Windows dynamic partitioning (SFS partitions) to a basic disk. This can be performed via tools such as TestDisk or EASEUS-Partition-Master / MiniTool-Partition-Wizard.
Are you sure you want to continue anyway? yes
Recommended repair: ____________________________________________________________
The default repair of the Boot-Repair utility will reinstall the grub-efi-amd64-signed of
nvme0n1p4,
using the following options: nvme0n1p1/boot/efi,
Additional repair will be performed: unhide-bootmenu-10s win-legacy-basic-fix use-standard-efi-file
/boot/efi added in nvme0n1p4/fstab
Quantity of real Windows: 2
Mount nvme0n1p1 on /mnt/boot-sav/nvme0n1p4/boot/efi

Unhide GRUB boot menu in nvme0n1p4/boot/grub/grub.cfg
An error occurred during the repair.
You can now reboot your computer.
Please do not forget to make your UEFI firmware boot on the Ubuntu 20.04.1 LTS entry (nvme0n1p1/EFI/ubuntu/shimx64.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\shimx64.efi
