I've been trying to dual boot Ubuntu 14.04 and Windows 8, on my HP Pavillion g6-2320. The installation got complete the first time, but Windows got booted. I tried installing again, but got errors,
grub-efi amd64-signed failed to install into /target/
grub-install /dev/sda failed
during different combinations of enabling/disabling Secure Boot/ Legacy Mode
I installed reFind Bootloader but still it didn't work. Now I used BootRepair, and I got reFind , with options for Windows and Ubuntu. But after using Windows once, now Windows gets booted by default - no reFind. I can still access reFind from BootOptions but now both its options load Windows 8. I can access Ubuntu by choosing the option from BootOptions. How to display grub/reFind screen on system startup ?
But in all cases where I'm accessing Ubuntu, the option "install release" is present. So is Ubuntu really installed in my system ?
I'm okay even with a solution requiring a reinstall of Ubuntu if other methods are hard. But do give me any advice on partitioning or Legacy/Secure boot, which would help me install Ubuntu without using bootrepair.
