Subject: [tclug-list] Can't boot from external drive

        Shalom

I'm having trouble booting from an external drive that
has a usb interface.  I can boot from the drive with
either of my laptops, but not from my desktop.  The
desktop has a fairly new gigabyte motherboard.  I've
tried different boot sequences, but it either boots from
the desktop's internal drive or it says:  Reboot and
select proper boot device or insert boot media in
selected boot device and press a key.
--------------------------
I've tried using different usb ports on the desktop.
The only idea I have is doing a bios update.  I don't
have any idea if that would help, but don't know what
else to try.  Any other ideas?  Thanks.

Is the boot device formatted for a legacy boot, or UEFI boot? Is the
desktop configured to boot that method?

Thanks, Jeff.  I tried again and found a bios switch that
I hadn't noticed related to legacy/uefi and now it's working.

Is the drive partitioned with a boot switch added? I seem to recall this being an issue with manually partitioned drives back before I didn’t care about partitioning.

Sweating it out, feeding the bugs in the boonies and I needed to play 
computer again. I was able to get my 64bit opensuse 42.3 to work with 
KDE by setting the display rendering from openGL2 to X11. Other choices 
were Wayland and openGL3. Must be some crazy advanced graphics cards out 
there!!

Now ambitious, I bought an opensuse 15.1 (latest) install DVD from ebay, 
because OSDisc.com just closed. It didn't work and in reading opensuse 
troubleshooting I learned the disc used SHA256 security to assure 
downloads and disc integrity. Very nice of them. Question: Do other 
distros do this???

And I browsed a little into their vast global download mirror system. 
When you try download from their German site users are redirected to a 
mirror site closer to you. So I'm feeling more ignorant the more I 
learn. I'm sure many TCLUGers know this stuff.

I actually like feeling ignorant. I saw a documentary, "The Ethanol 
Effect," and learned a little more about the Stanford University "Center 
for Quantum Molecular Design." So I'm delighted smart people think 
photochemistry and cellulose biofuel is a good renewable energy idea.

Wonderful to see smart young people doing great things.

Most if not all distributions of Linux (and other software thingies) publish
checksums (MD5, SHA) for individual packages and other things for the sole
purpose of avoiding injections of mallicious software in their distribution.
The chain of trust, of course, heavily relies on how the checksums are
published (on web-pages), which inevitably turns to HTTPS and the idea of
website certification.

Yes, these things are mostly unspoken and ignore by downloaders -- including
the guy typing this message.

I learned this when an opensuse install disk refused to install. A 
"media check" in the configuration tool YAST declared the disc sha256 
wrong. So opensuse implemented the protection mechanism without me aware 
of any of it. Again, surprised by the professionalism.

The other two mentions: Detroit Public TV documentary "The Ethanol 
Effect," and Stanford University "Center for Quantum Molecular Design 
(CQMD)" pertain to advancing "Green Energy" technology.

CQMD is developing computer modeling that some of your associates might 
be aware of. When we discussed this before, you got close to some 
science. But I believe this Stanford group is spot on. This research 
field has become a global race.

My frustration is actually doing sweaty grunt preliminaries. We are 
buried in advanced biomass potential in Minnesota. The ridiculous city 
politicos say all we gotta do is have some new expensive "policy." 
Hopefully, someone Googles the two references provided.
