Re: Bug: Buster 10.0 Testing 20190617 Image LiveCD Will Not Boot

Hello Pipo,
Regarding your suggestions:
1) To video record with phone has been one thought I have had.
The challenge is the message flashes so fast as human I cannot
even see the messages, just the fact the messages occur. I
tried adding "debug" to the boot command parameters in hopes
that might show the messages in some more tangible manner that
in essence did not change the challenge to see the messages.
2) I do not think firmware is an issue as I have no problems
with the same problem Buster 10 Testing image if I choose any
other option on the splash screen than the Live Image option.
In addition I have no problems booting to Live image with
Lubuntu or Xubuntu for versions 19.04, 18.04, 16.04, 15.04, nor
with Linux Mint, nor with Knoppix, nor Centos, and many more on
both Lenovo systems (laptop and desktop). I also had no
problems booting Debian Jessie 8 Live. These Live Image boot
problems started with Debian 9 Stretch, but due to the odd
nature of the bug I have played the bugs in manner to enable
me to boot to Live Image for Debian 9 Stretch. All of these
cross tests points in my extensive QA/Systems/OS testing
experience to a problem with how Debian vs other Debian based
Live Images effect the boot from the Splash Menu, ie the
commands used to boot the Live Image as that is what Debian
10 Buster Testing is showing, but I cannot capture it with
pic or video as the message flashes so fast one cannot
really see the message.
As an important side issue it seems to me if there is an error
due to some command parameter to boot from the splash screen
then the process used to boot via those commands should also
have method to pause to show the errors encountered. I am
spending alot of time again trying to report obvious error
with error messages that do not provide a means to obtain
the error messages the Live Boot is providing. That causes
the reporting of the issue and error to be one of between a
rock and hard place void.
