I just updated 16.04 (I sometimes sudo apt update then upgrade) by
clicking install updates when then box popped up (HP x360 4109NA running
normal 16.04 / unity, nothing particularly exotic). It wanted a restart
so I closed Firefox and Thunderbird so nothing else was open and hit
restart.
I was told "No boot device found" by my UEFI BIOS, with no change after
several reboots. I had to ESC on boot, select efi file manually and
choose grubx64, now I'm back in and wondering how this could happen.
The only thing I can think of which is slightly unusual about my
environment is the fact that while installing those recent updates (one
of which had something to do with shimx64 and a warning about secure
boot in the notes - I don't have secure boot on) I had firefox open, but
in a firejail sandbox (firejail firefox). Maybe the awesome Firejail is
not involved, I just can't think what else is so unusual about my
environment that I'm not seeing many other people complaining of this.
The message I consistently received upon cold booting / rebooting is:
***
Boot Device Not Found
Please install an operating system on you hard disk.
Hard Disk - (3F0)
F2 System Diagnostics
For more information visit <HP website>
***
I was consistently able to get back in to the system by hitting ESC,
choosing to boot from EFI file and then selecting grubx64.efi or the
shim.
I did try F2 and ran a test on the disk but it's fine.
I don't know much the first few moments of boot so I'm assuming I wen't
down the wrong path but I did get back in and played around a bit with
efibootcfg:
$efibootcfg
Timeout: 0 seconds
BootOrder: 0001,9999,0006
Boot0001* Qubes
Boot0006 Windows Boot Manager
Boot9999* USB Drive (UEFI)
Which is weird, no mention of ubuntu, only Qubes which I (maybe?! - I
thought I just wrote it to USB and installed it on my T420 but maybe I'm
wrong) must have live booted once from a USB stick 6 weeks ago.
so I:
sudo efibootmgr -b 1 -B
sudo efibootmgr -b 6 -B
sudo efibootmgr -c \\EFI\\ubuntu\\grubx64.efi -L Ubuntu
And ubuntu ended up first in the list at 0000 ... and still wouldn't
boot normally, I got the same error and had to select efi file manually.
Going into my UEFI BIOS and hitting return on "OS Boot Menu" which was
in the #1 spot lead to a message similar to "OS Boot menu not found"
I got frustrated and formatted my disk, reinstalled everything etc. and
now everything is fine except my bluetooth mouse refuses to work, but
I'm sure that's another story.
