I have a laptop with a pre-installed Windows 10. I wanted to switch to ubuntu, but I decided to leave windows installed in case ubuntu's installation doesn't work. So I created a new partition and installed ubuntu 16 LTS on it in uefi mode, using a live USB made by Rufus. Ubuntu was installed successfully and restarted. But Windows quickly loaded as if nothing happened. And I can't access Ubuntu. Even by holding Shift+Restart and chosing Ubuntu.
I tried every solution I found especially those mentionned in :

I used the command bcdedit to set the path to ubuntu
C:\WINDOWS\system32>bcdedit

I started Live CD version of ubuntu to copy shimx64.efi to /EFI/Boot and /EFI/Microsoft/Boot and renamed it to Bootx64.efi and Bootmgfw.efi using a Terminal. And when I restarted, nothing happened and I got this error :
Insert system disk in drive,
Press any key when ready....
Then I restored back the boot files, and retried with Boot-Repair's recommended repair. Restarted, and I got the same previous error...
I also can't choose ubuntu to boot first from Uefi boot in bios setting, as I find only HDD/SSD, USB memory, ODD, LAN1, LAN2 .... Same when executing the command efibootmgr .
Please help me. I wasted an entire day trying differents solutions as nothing seem to work out for me.
