I installed Ubuntu 17.04 from a USB on my Acer Spin 5 which came with Windows 10. I made the choice of removing Win10 because earlier when I Dual-booted Ubuntu and Windows 10 I was not able to boot into Ubuntu after a Windows update.
Now when I start my computer it says
Default boot device missing or boot failed. Insert recovery media and hit any key, Then select "boot manager" to choose a new boot device or to boot recovery media
If entering this I only get the choice of booting with Windows Boot Manager which takes me back to this screen again, I'm also able to use my live-USB with Ubuntu and either load into Ubuntu live or install directly, both this options brings me back to the "Default boot device…" after a reboot. I've also tried boot repair with the following commands
sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update sudo apt-get install -y boot-repair && boot-repair
But now after reboot I get
Failed to open \EFI\Boot\grubx64.efi - Not found Failed to load image \EFI\grubx64.efi: Not found start_image() returned Not found Failed to open "\EFI\BOOT\Microsoft\grubx64.efi - Not found Failed to load image \EFI\Microsoft\BOOT\grubx64.efi Not found start_image() returned Not found
How do I solve this problem with not being able to get into Ubuntu?
How do I know which partition is my main partition?
sudo fdisk -l
