Hi. All my rigs are already working on Windows Server 2016. I have already tried HiveOS on one of from a flash stick. It's ok, but I've read here that HiveOS rather quickly kills the flash drive because it has swithed on the file system logging. That is, it is better to use SSD. Moreover, there is enough free space on them (60GB).
But how do I install HiveOS on an existing Windows system so that when I log in I have a menu with a timer and default system (HiveOS) and second spare system (Win)? I did not find it anywhere.
