Mmm I try to explain better
When I started the iso
After the question of data and apps, the iso began the upgrade
The screen changed and showed me for a little a screen of the progress, but this happened only for a little
After that the machine rebooted itself, and only one time
When it turned on again, there wasn’t anything about the install, and all files I had on desktop were all to the left...
If you want I can take a photo with my phone
