I have recently had a similar problem with a fresh install of Ubuntu Server,
versions 14.04.1, 14.04.3, and 15.04 on an HP Pavilion 15-f039wv laptop. I
have a factory pre-installed version of Windows 8.1 that should be dual booting
under UEFI with Ubuntu Server from the same hard disk. However once the
install is complete, the machine only boots to Windows, unless I first
intervene by pressing F9 to get an UEFI "Boot Option Menu" that offers three
options of:
OS boot Manager (UEFI) - Windows Boot Manager (ST500LT012-1DG142)
OS boot Manager (UEFI) - ubuntu (ST500LT012-1DG142)
Boot From EFI File
With the second option, I can boot to a Gnu Grub screen and then to
Ubuntu Server.
In Ubuntu server, I can use efibootmgr to display its firmware
parameters. I can set a next boot number and have it take effect for
the next boot, but as expected, only for the next boot, and I can set
the timeout value and have it persist across multiple boots. However
while I can change the BootOrder and display it with both efibootmgr and
in the /proc file system, the change to the BootOrder is reverted to the
original version (Windows Boot Manager first) if I reboot, even if I
reboot directly back to Ubuntu using the F9 intervention.
I have seen numerous postings in forums addressing this kind of problem
and which often that attribute the problem to aggressive, nonstandard
UEFI behavior from the system vendors (HP in my case). At least one,
http://askubuntu.com/questions/221835/installing-ubuntu-on-a-pre-
installed-windows-with-uefi, has a popular answer that claims in a
recent edit that the problem is fixed in Ubuntu 15.04. It is not fixed
in Ubuntu Server 15.04, at least not in my case.
This is particularly a problem in my case because the current behavior
requiring an F9 intervention to select a boot manager, prevents remote
or other unattended rebooting of the Ubuntu server, for example when
using SSH for maintenance.
