I installed Ubuntu 15.10 along with my Windows 10 installation. I first changed the boot order on my BIOS as follow:
- CDrom
- Windows Boot manager
Then, I chose to install Ubuntu in a "Dual Boot" configuration. Everything went fine and at the reboot grub was there. If I choose Ubuntu, I boot to Ubuntu. If I choose Windows 10 I get a blue screen:
Recovery
Your PC/Device needs to be repaired
A required device isn't connected or can't be accessed
0xC000000E
Enter to continue
F8 for startup settings
None of the two options works (I stick to this screen).
Now, If I go back to my BIOS settings and place Windows boot manager
on the first position, Windows boot, but grub does not show.
It seems that Windows absolutely want its Windows boot manager
to be first.
I don't have any Secure Boot
option available anywhere.
How to fix this problem?
