Using a fresh/new SD or USB resolves the problem. But the question
remains: how can I destroy any relevant GPT information on a Flash
drive (or even harddisk) to avoid unwanted remains of an foul image
installation?
First guess was to write the last couple of bytes on such a flash drive
by letting dd(1) counting backwards, but I couldn't figure out how to
let dd(1) do such a procedure. The nightmare didn't end, while trying,
the SD flash card died :-(
I use dd if=/dev/zero almost everytime when I need to install system on
used HDD.
I rewrite about 10MB on its start and then about 10MB on the end.
I have some script to do this - simply takes media size from diskinfo
command, substract 10MB and then dd with seek
Hope that it will help you
