To all owners of the ASUS U43F laptop.
Here is what the tech support from ASUS told me about this laptop:
"We apologize for any inconvenience or frustration this may have caused. The reason you are having issues updating is this unit does not support 8.1 or 10. It was designed and we only claim it supports windows 7. So if you were able to install 8, thats more than what we claim it will support. We deeply apologize for this matter, but this unit does not appear it will have windows 10 support. "
They have no intentions of helping or solving the upgrade issue with these laptops. We are stuck with what it is!!!
