Yes but that wasn’t the problem.
In funcs.sh script, I saw:
case $osid in
[1-2])
.
.
.
[5-7]|9)
.
.
And missing *) in the case test, so only 1,2,5,6,7,9 partition types were correctly tested.
And my image was 50 type (linux)
But these lines in funcs.sh have been totally rewrited, now the last case test is present
Thx
