OK, I downloaded the Zorin OS Lite version and was trying to install it alongside Windows 11 Pro: AND FAILED! To even come to that point was needed as little as 1h7min!
Overall, in that install process, nothing told about Zorin OS 16 Lite, just Zorin OS 16!
I'm still stacked at At the Installation type which let me just choose Erase Disk..... or Something else! It mentions that this computer has no detected operating system! Windows 11 Pro was just installed clean before on a 150GB HDD Partition and fully activated as well. Running with no problems.
Tha Laptop used for that all is an Acer Aspire One 722 with Dual AMD CPU C60 and 8GB Memory! It was working before with Zorin OS16 Core alongside Windows 11 Pro with no problems on the same HDD (a WD Black Scorpio 500GB 7200rpm)!
The USB Stick used seems to be no problem and the Checksum test of it went 100% clean!
So, what the hell is going on? Any idea?
Thanks a lot for any useful info.
