Dear all,
For a course in Ivory Coast I want to distribute USB sticks with Lubuntu
Linux and a Docker container inside. Docker works only for 64 bits OS,
so I need a 64 bits version.
Since I don't know whether the students' computers work with BIOS or
UEFI, it would be great to create bootable pendrives that work for any
computer.
I studied a bit about syslinux and found this very complicated, and also
very risky. This is simply too much for me.
I looked around further and found this site:
https://help.ubuntu.com/community/Installation/UEFI-and-BIOS
<https://help.ubuntu.com/community/Installation/UEFI-and-BIOS>
with a repository of images at:
http://phillw.net/isos/linux-tools/uefi-n-bios/
made by Phil Whiteside. That looks wonderful. My question is now: is
there also a 64 bit version available? For some it is explicitely
indicated that they are meant for i386 (so I should not use them), but I
feel unsure about the other ones.
Also: we buy either 8GB or 16 GB pendrives. Which image would work best?
Best regards,
Wilbert
Dear Wilbert,
The UEFI-and-BIOS systems dated May 2016 are 64-bit. These systems are
*installed* systems (can be installed into USB sticks, SSDs, HDDs or
memory cards, and works like a normal installed system).
If you intend to use the USB sticks also for installing systems into
other computers, it might be a good idea to have live systems or
persistent live systems. The Lubuntu 64-bit iso files can also boot in
both BIOS and UEFI mode.
Is it possible that some student has a 32-bit computer? You can make
persistent live systems with 32-bit Lubuntu, that can boot in both
32-bit computers and 64-bit computers, and in both BIOS and UEFI mode.
This is when you use the usb-pack-efi for booting.
So maybe you should make some master USB sticks just to check that they
work for you, and maybe bring more than one configuration, even if I
understand that the focus is on 64-bit systems.

It is much easier to find USB 3 pendrives with good performance among
those with 16 GB. See this link and links from it for details about the
data transfer speed of pendrives.
