<p>Hi Jochen -</p>
<p> thank you for this thorough documented test case. I also
experienced in the USA, several models of modern laptop that
prevent booting from USB in non-obvious ways. Sometimes this is
documented; it was always the low cost models in my tests.</p>
<p> regarding Macs and NTFS, Apple has stubbornly and for their own
interest, declined to support basic data exchange with standard
Linux format volumes, and mostly also Windows-style volumes. Your
workaround is not one I tried, but, I gave up this effort myself
long ago. Apple is obstructing this basic functionality and they
know it well. Others on this list are talking about M1 processor
Macs, and how to approach those. I wish it all well.</p>
<p> thank you and best from Berkeley, Calif --Brian M Hamlin

<div>Let me start with the positive news: I distributed a 32 GB
flash drive to my 20 students and a good number of them could
happily boot from the NTFS-formatted flash drive and proceed.
It all works well on the eight-years old Dell computers in our
labs.</div>
<div><br>
</div>
<div>But I have not succeeded to help any of my Macintosh
students and ran into significant troubles with Lenovo and HP
laptops.</div>
<div><br>
</div>
<div>On the Mac side, I concluded that I needed to format the
OSGeo-live partition to HFS+. I then proceeded to use the
Linux 'dd' command to copy the iso file to the first
partition, which resulted in the partition format to switch to
"ISO9660". The resulting flash drive is still not detected on
a variety of Macs</div>
<div>
<ul>
<li>Macbook Air (retina 13” 2019) , Intel(R) Core(TM)
i5-8210Y CPU @ 1.60GHz, Mac OS Big Sur version 11.6.</li>
<li>MacBook Pro, 13-inch, 2020, four thunderbolt 3 ports;
CPU: 2 GHz Quad-Core Intel Core i5</li>
</ul>
</div>
<div>Lenovo ThinkPads and IdeaPads apparently cannot read boot
drives that are NTFS formatted but once I go back to FAT32,
they boot properly. Having said that, the Lubuntu system does
not recognize the built-in network cards and hence fails to
connect both via ethernet cable or wireless.</div>
<div><br>
</div>
<div>HP laptops work only if "secure boot" is disabled in the
BIOS and "legacy support" enabled. Unfortunately, newer HP
laptops don't seem to have the legacy boot option anymore and
so we are here stuck again with the flash drive being
invisible to my students.</div>
<div><br>
</div>
<div>The last time I taught my Advanced GIS course with
OSGeo-live flash drives was in 2019 and back then I did not
encounter any of the above problems. </div>
<div><br>
</div>
<div>So, after all this preambulation, here are my questions:</div>
<div>
<ol>
<li>What do I need to do the get my Mac students set up (I
do not have a Mac and therefore need more hand
holding here)</li>
<li>Is there a website (I searched the listserv archives to
no avail) that collects FAQs about installation problems?</li>
<li>Assuming that there is not, are there readers of this
message who have successfully circumvented the problems
described with newer laptops?</li>
</ol>
I could be wrong but I believe that a bit of this is due to
the distribution being Lubuntu based, which has a much small
community that may not be as up-to-date with modern BIOS as
other, larger Linux distributions. Given that we are beyond
the days of DVDs, might we perhaps return to one of the
heavyweights (Ubuntu, Fedora, Debian)?</div>
<div>And a second suggestion: could the organizers of this
listserv create a FAQ related to installation issues? The
support in that respect is small and outdated. I would be
happy to populate it with what I have learned so far.</div>
<div><br>
</div>
<div>Cheers,</div>
<div> Jochen</div>
