Hi Peter, [ Peter Ehlert, 2021-06-20 ]I just installed EDU using firmware-edu-10.10.0-amd64-netinst.iso on a USB stick. The installer is the traditional DI that I am accustomed to, but setup very differently.Yes. Debian Edu is a subset of Debian aimed at setting up a network for schools or similar organisations; the installer sports a profile choice page, and all needed information is gathered at the beginning of an installation. See the projects landing page: https://blends.debian.org/edu/ containing links to all needed resources, including the manual.It detected the network and all seemed fine...Good.I created a 30 GB root partition, 10 GB swap, and a 50 GB home. I deselected the other swap partitions for the other OSs on that computer. I did not install a boot loader by choice. Installer complained as expected... I told it to continue restarted and booted on my default Debian 10 Mate, then update GRUB.I guess I don't understand your intention. Installing Debian Edu together with other distributions like you tried it is only supposed to work if you'd choose the 'Standalone' profile, see the manual.
First boot: I could not login as a user "wrong password". anyway, I logged in as root. the boot splash screen says it is fails to connect to the network XFCE tools are alien to me, so that does not help.All these issues seem to indicate that your choice on the profile page has been something else than 'Standalone'.
How do I start?Please read the manual. Wolfgang
