Hi alienpup,
thank you for trying it out!

Ouch… "interesting"! I've looked this up online and could find
no occurrence of this problem.
I'd like to make sure I understand when exactly this happens.
Am I guessing right that it happens:
- after you've elected to boot from the Tails USB stick
- before you see the GRUB bootloader with the Tails logo in the
background
?
Also, how did you install our experimental USB image on this USB stick?
It would be interesting to know if Debian boots on this machine, with
Secure Boot enabled:

That's a good start. The output of the following commands would help
me identify this computer more precisely and look the problem up
online:
sudo dmidecode -s system-manufacturer
sudo dmidecode -s system-product-name
sudo dmidecode -s system-version
