I originally posted my problem in the German language forum accidentally. I did not notice there were two sections.
I installed Univention Corporate Server and it went as good as can be. Upon reboot it states: “Reboot and Select proper Boot Device[…]”
There is only one possible boot device in there, the hard drive UCS was installed on. The hard drive is used, and a seagate, so it could be bad. I am not a Linux person (yet) so I am not certain how to proceed. I can load the installation USB and tell it to “Boot from first hard drive”, but that leads to more errors. Such as—Okay now it won’t even generate the errors. It just beeps and comes back to the main menu.
Another poster suggested using a different hard drive, since a defective HD could be the culprit. So I used a brand new one…same result.
If I load the installation media and select “boot from first hard drive” it goes straight into Rescue Mode asking me for my language.
So,I burned a disc of UCS, instead of a USB drive, loaded it successfully, selected Load First Hard Drive,and it says… “Booting…”
Just “Booting…”. It does not get past “Booting…”
I am performing another install on different hardware. Who knows, it could have been that Gateway desktop. Hopefully it works fine this time…
