We have NVIDIA GeForce 705/ NVIDIA nForce 630a and because of this I can't upgrade to Windows 10. What can I do to fix this for the upgrade?
Many users encountered this issue and the only way to do it is with the help of Windows Media Creation Tool and a USB stick (8 GB or more).
I recommend downloading the Media Creation to create a bootable installer. Download using the link posted below.
Once the stick is done, reboot the PC and boot from the USB then continue the installation.
