Ok, now I think I understand what hapen...|
VI8 Plus do not have the same hardware depending it is originally a single or dual os, so do not need the same driver.
So even it you want to reinstall your dual OS in Single OS Win (like I wanted to do), you should not use the image or driver of the single OS, but the image and drivers of the dual Os, once again, even if you install just only Win.
Unfortunatly, I did not find any Win dual OS drivers !
So, I have install the Win image here of the dual OS, and it was working perfectly. But it is an old image of Win (difficult to upgrade with the disk size of the take, even in single os), and including some things for dual OS.
So I wanted to do a fresh install.
Before that I used double driver software to capture all my drivers on a USB.
Then I have done a fresh install from Microsoft ISO, and reinstall driver with double driver software.
Do not install drivers directly, some will not work, but if you use the restore feature of double driver software it will work for all including BT and touch screen.
For sure to do all that you will need a OTG USB hub with at least two USB ports as the touch screen and wifi will not work, so you need to plug a keyboard or mouse + the USB key with the driver and double driver software...
Hope it will help others.
