Angelos,
my recent changes give me a working isohybrid+UEFI ISO with GeoServer
2.10.0 + NetCDF extension, combined in this new branch for your
nightly-building convenience:
https://github.com/bencaradocdavies/OSGeoLive/tree/devel
I have submitted the individual changes as separate pull requests.
Kind regards,
Ben.
