I recently got a new Acer-spin laptop, it has pre-installed Windows 10. I have installed Dual-boot Ubuntu before, just never using UEFI (always BIOS). I want to Dual-boot with Ubuntu 14.04, however when I finished installing (via Install alongside option NOT "Something Else". But the computer boots directly to Windows 10. So I have checked various forums now and this is everything I have tried:
Disabled Secure Boot
Disabled Fast Boot
Tried to boot from live usb Ubuntu and reinstall grub (however I was unable to keep up, when following error showed up "Cannot find EFI directory")
Any other suggestions??
