I've tried upgrading to Windows 10 from 8.1 using the Get Windows 10 app and also using WIndows 10 media download tool. I failed all the time. And when I asked Microsoft Support they said my dell model is not supported for Windows 10 upgrade and in Dell site too it says this model in not suitable for Windows 10. So is there any work around for this ?
Additional Information :
This is the error code I got Error C1900101-20004 . I removed all external devices during the upgrade process and my C drive had 35 GB free space. My hidden recovery drive is 100 MB
