I tried many time to install the Windows 10 on my Dell Laptop for many reason.
The first reason is the wall at 75 % of the Update to Windows 10 by a Windows 8.1. I have remove my Windows 8.1 and after install I take a new Windows 8.1.
Crash 75% or 80% on the black screen progressbar [Solved] use the medial Tools.
After to call the technical service. I tried the media Tools Creator. It's very good and fast for compare with the soft GWX.exe.
Today, Congratulation Windows 10 installed. I'm happy, but I look the Windows 10 drivers update. And, I look many error on Dell drivers (example: Synaptic, etc...). I try to restart my computer. The update installed. I restarted and I try to connect at my user session. And, Crash on my desktop... Freeze Screen.
Crash input/mouse [Solved] use the usb install. (but it's not free and not valid your native licence 8/7)
I gone to call the technical service for more information ... And Nothing.
I looked the dell support page and It's okay for Windows 10.
I try to rinstall an OS Windows 10 by USB on a Legacy and UEFI mode. It's the same problem. But, for the methode I have two error on the native intel graphical card.
