Today we released an updated Netrunner 17.01.2 Desktop ISO, which ships the just released version 3.0 of Calamares Installer and KPMCore 3.0.2.
This hopefully will fix the UEFI bootloader issues that some people reported, so if you experienced those with the previous ISO, this might fix it.
To help improve Netrunner further, please report any issues in our forums or in case of installer issues also on calamares.io/bugs.
