Hi Thomas,

Ok. size does not matter

The first message is the boot prompt. Then the usual messages· PCI found and so 
on.

Last message is, that a new USB device is found, then the screen goes blank. I 
can make some snapshots of a video, by interest.

> Can you determine the origin of the last visible messages ?

Yes, see above.
> BIOS/EFI ?

The BIOS is without EFI.

> Boot loader (GRUB or ISOLINUX/SYSLINUX) ?

Bootloader is grub, the image is an image from kali linux. The big size comes 
from a virtualbox image inside for windows 10. (the vmdk is smaller than 4GB, 
so bootcdwrite got not into problems).

> Linux ?

Yes, KALI Linux, which is Debian based.
> Debian installation software ?

vers close to.

Yes, it uses legacy bios.

Yes, it is. The image is about 32 GB big, the USB-stick is 64GB. Should fit 
very well. The last ISO working was baout 12GB and fit on a 32GB stick.

Yes, it can. I tried also dd with option bs=1, so to install bitwise, just to 
make clear everything is copied.

I already tried thzis, too. 1024, 2048 and 4096, and of course 1.

Already did, comarision was ok.

This stick is new. However, the stck I used before, was another distributor. I 
changed the stick, because the former stick I used before, died after about 
10th or 12th installing of the iso.
