I ran into some trouble trying to start Ubuntu 14 in a new laptop with Windows 8.1 preinstalled. However, the booting process is kind of uncomfortable now.
When I start the laptop first I can see the Windows boot manager with Windows 8.1 as the only option. Then, I found out that pressing
esc leads to grub, and then I can run Ubuntu. I don't know how this happened, but after hours trying to be able to start Ubuntu unsuccessfuly now I am more than happy.
So now I just want to have both options (and future options) in the same boot manager, I honestly don't care if it's the Windows boot manager or grub.
I tried following this answer but it didn't work.
What can I do?
