Hi Jochen -
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.
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.
thank you and best from Berkeley, Calif --Brian M Hamlin /

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.
But I have not succeeded to help any of my Macintosh students and ran
into significant troubles with Lenovo and HP laptops.
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
* Macbook Air (retina 13” 2019) , Intel(R) Core(TM) i5-8210Y CPU @
1.60GHz, Mac OS Big Sur version 11.6.
* MacBook Pro, 13-inch, 2020, four thunderbolt 3 ports; CPU: 2 GHz
Quad-Core Intel Core i5
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.
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.
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.
So, after all this preambulation, here are my questions:
1. 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)
2. Is there a website (I searched the listserv archives to no avail)
that collects FAQs about installation problems?
3. Assuming that there is not, are there readers of this message who
have successfully circumvented the problems described with newer
laptops?
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)?
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.
Cheers,
Jochen
