Is the reason for these failures known ?
Can it be high boot image addresses and the partly uninitialized
32 bit processor register ?

Whatever, i asked about isohybrid because this brings its own
partitioning.

The two failure messages indicate that some file access does not
work. If it is about partitions and/or file addresses, and if it
happens with isohybrids too, then we have a path for experiments.
If isohybrid does not show the problem, then we have a difference
which might help to find the problem trigger.

Maybe it is all random. More variations should tell.


To Ronald F. Guilmette:
I assume that the content of the USB drive can be read without
errors after the machine was booted by some means.
Was this already tested ?


Have a nice day :)
