I have tried both online and DVD updates more than 10 times , factory restored 3-4 times.
Tried every tip on internet too. ALWAYS FAILED.
Is there anyone managed to install Win10 ?
To add more details:
I always delete the C:\WINDOWS~BT
I always delete the C:\WINDOWS\SoftwareDistribution\Download\
I tried uninstalling ALL the software AND drivers except Intel Display and touchpad.
I tried install also from USB.
I am trying from Monday , i am convinced that this won't do at all.
My next try is to install clean Win8.1 Greek from Microsoft creation tool (no Dell , no Apps) and then upgrade to 10.
Update: Clean Installed Win8.1 ENG-US (DVD) , it activated normally (my original was GR version).
So i have a clean ENG 8.1 Home - no drivers at all , no Dell add-ons , only 2 partitions (OS and Reserved 350MB.
Tried installing now Win10 ENG-US Home (DVD) .... and still that error !!!!!
Something Happened. Windows installation failed!
...and i'm still wondering ...Dell says 3543 is compatible with Win10....
Am i un-Laki ?
Well i did was unlucky.
My problem was a rare situation where i was using 'system' as computer name and 'user' as username.
According to googling i found that 'SYSTEM' is not a valid computer name , and someone else also had windows update problems due to that.
So i post my solution in case it helps someone.
Do you mean that if I use "system" as a username windows 10 will not been installed?
it's a wonder information HH
thank you anyway
Hope you resolved the problem
'system' as a computername .
Anyway one of the both above was causing the installation to fail.
