Hi
There were some emails to this to do with putting Linux distros on a new UEFI of mine. Since the last LUG meeting (since I been doing other things etc), I still have a test install of Ubuntu 15.04. The plan is to multi boot the laptop with Windows and more than one Linux distro.
My test install of Ubuntu can be booted up, but to begin with have to hold down esc for long enough or Windows will get booted up instead. Ubuntu points to the Windows UEFI I think, and both are installed in UEFI mode it seems, and apparently not meant to try and mix UEFI and legacy mode OS installs. Saying that legacy mode has not been enabled anyway, but yes secure boot has been disabled.
When esc is held down for long enough the Startup Menu comes up, with options for System Information, System Diagnostics, System Recovery, and importantly this is also the menu with options for a Boot Device Options. On this particular laptop the BIOS Setup seems quite limited really in what it can actually do, for example according to the Ubuntu UEFI page was apparently meant to disable fast boot, but I don't even get options for things like that, on that HP Pavilion x360 convertible.
Once F9 has been selected as in the boot options, the boot manager comes up with options for the Windows OS Boot Manager (UEFI) and the Ubuntu OS Boot Manager (UEFi) and a Boot From EFI File option. If the Windows option is selected it loads up the HP logo screen and Windows then boots up. If the Ubuntu option is selected it loads up Grub and as would expected from there can load up Ubuntu or even Windows. However the big question is: Can I get it to come up with Grub first when the computer is turned on or rebooted, and then to be used to load up Linux or Windows, and if so how? Someone at the LUG last time thought it should be able to be done, and I agree, but how? Or is this just an example of newer is not always better? I mean on a old BIOS computer this would have generally been quite easy to do, to have Grub coming up first, but yes it's a different ball game with UEFI.
Thanks in advanced for any help.
Regards
Sebastian

Hi
It's another LUG meeting tomorrow at our usual Knights Templar Pub in Temple Quay near Temple Meads Train Station and Broadmead.
Who is intending on being there? I'll probably be there about 2:30 or about 3pm.
For anyone that does not know the meeting is very informal, with an opportunity to show or give away interesting Linux/tech related things even if wanting to, or just come along for a chat etc. I have another device that runs Linux :), that I can show tomorrow. We usually sit on the lower level at the back of the pub when entering it in the left hand side corner with the plugs, or near there instead if someone is already there. People turn up and leave when they decide to, with most attendees usually being there about 2pm, and leaving between 4pm and 5:30pm.
Regards
Sebastian

You need to install the package efibootmgr package and you can use this to
select the default boot ordering from Linux.
There is a windows command line utility that does the same kind of thing,
but windows.
My EFI BIOS also allows you to change the default, but I wouldn't be
surprised if that was optional for the BIOS to support changing it.

I'm planning to be with you this month.
All the best,

Ok thanks :) I'll look into that, and I assume the other two distros I would like psyichal installs of have the same package or something similar, in the repos at least. I'll probably do a progress update on this list, next week or something like that.

Subject: [bristol] SSD alignment
Message-ID: <55B2B79B.909@gmail.com>
Content-Type: text/plain; charset="utf-8"
Hi,
Does anyone have a feel for whether SSD alignment is something that
needs careful attention with modern SSDs and a recent version of Linux?
The last time I dealt with partitioning an SSD was several years ago,
and I remember needing to be careful about aligning the partitions along
4KiB boundaries, and that aligning along erase block size boundaries was
also important. I had to do this manually at the time, as the various
tools had not been updated to support SSDs and the defaults would give
incorrect alignment.
Now I have a very new Samsung 850 EVO 500GB SSD which I want to
partition, so I can install Ubuntu on it. I have read conflicting
reports online about whether alignment is something you still need to
bother with. The received wisdom seems to be that you should just align
partitions to 1 MiB boundaries, and that you probably don't need to
worry anyway since most modern partitioning tools do this anyway.
As far as I can tell, the erase block size should not matter for
partition alignment (I don't understand why it would, anyway, since for
SSDs it is so much larger than the sector size).
If anyone has any experience or thoughts on this, I would be interested
to hear!
Thanks,
James
