Ubuntu: trying to setup ubuntu14 with Windows 10


I already have Windows 10 installed. I created the recovery drive for Windows. I turned off fast boot but did not turn off safe login. I created a partition using Windows partition manager. I then used the Ubuntu installation flash drive to create three partitions (2 ext4 for "/" and "/home" and one for swap space). The installation seemed to have gone fine. When I start the computer, the boot loader only boots up Windows 10. I tried BC Edit with Windows 8.1 and was able to get it working though not perfectly. I read up that perhaps I should not have to use EasyBCD with Windows10. Any ideas on how I can modify the boot loader to ensure that I can launch either Windows 10 or Ubuntu 14 (on a HP laptop).

Thanks in advance


Try to change the default operating system to boot from Windows to Ubuntu in BIOS / UEFI.
If this is not possible or doesn't work with expected results proceed with the following steps:

First you have to disable hibernation in Windows - as you said Fast Boot is disabled already.

Boot into Windows - open command prompt as administrator and execute this command:

powercfg /h off    

Shutdown the machine (do NOT reboot) completely.

Then reinstall GRUB bootloader to your Ubuntu installation in EFI mode.

Boot from the Ubuntu install media - then open a terminal and execute:

sudo mount /dev/sd*** /mnt  sudo mount /dev/sd** /mnt/boot/efi  for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done  sudo chroot /mnt  grub-install /dev/sd*  update-grub    

Note :

sd* = disk | sd** = efi partition | sd*** = system partition

In case you have an older machine with legacy BIOS the commands are:

sudo mount /dev/sd** /mnt    sudo grub-install --boot-directory=/mnt/boot /dev/sd*  

Note : sd* = disk | sd** = system partition

If you do not know the partition numbers you can easily identify them with GParted.

This (Graphic User Interface) tool is already included in the Ubuntu installation media.
