I have a PC with Windows 10 and I need to install Ubuntu 14.04 alongside it. I followed the exact same steps I found online and yet, after installing Ubuntu, the computer boots directly into Windows 10. Here is what I did:
Downloaded the ISO of Ubuntu 14.04 LTS
Put said ISO onto a USB drive with Rufus
Deallocated 60 GB from my C: HDD (I only have a 1TB HDD, no SSD). So far, so good.
Disabled fast startup
Restart into the UEFI system, boot from device
at this point, aside from the CD/DVD boot option, I see a "LINPUS LITE USB" and "EFI USB BOOT". If I choose the latter, a screen appears saying that there is no bootable USB device, then redirects me to a screen where I can choose between Windows 10 and, again, Linpus Lite. I pick Linpus Lite and it finally boot into Ubuntu
I select "try Ubuntu", proceed to install and restart the computer.
At this point, I have no way to boot into Ubuntu. It goes straight to Windows 10 and, even in the boot menu of the UEFI screen, I have no option whatsoever that allows me into the Ubuntu partition. I even tried to install the boot repair but "cannot locate package". What went wrong? Why isn't the grub appearing? I also tried disabling the Secure Boot but nothing changed.
