Fix WINDOW10 and Ubuntu dual system installation no boot options issues

There are many examples of win10 and Ubuntu dual-system installation online, and this is not the case.

Today's newly bought notebook, want to install dual system. There are no options after the normal installation of Ubuntu reboots.

Workaround One

After downloading and decompression, follow the steps below to install the refind.

1. Back to Desktop
2. Right-click the Start button and select Admin command line
3. Input Mountvol g:/s (this maps your EFI directory structure to G-disk)
4. Enter the extracted Refind directory. For example: CD c:\users\gary\downloads\refind-bin-0.8.4\refind-bin-0.8.4. When you enter the dir command, you can see a refind directory
5. Enter the following command to copy the Refind to the EFI boot area xcopy/e refind g:\EFI\refind\
6. Enter the following command to enter the Refind folder CD G:\EFI\refind
7. Renaming the sample configuration file Rename Refind.conf-sample refind.conf
8. Run the following command to set Refind to bootstrapper bcdedit/set {bootmgr} path \efi\refind\refind_x64.efi
9. Restart your computer
10. You'll see a graphical menu with Ubuntu and Windows

This process is very similar to choosing the Grub boot program.

Simply put, the main is to download Refind, unzip the file. Copy the file to the EFI boot area, rename the configuration file, and then set the Refind as the boot program.
