I have a Gateway PC with an AMD Radeon HD 6750 graphics card. Attempting to do the Windows upgrade always fails. If I do an install of the creator version it succeeds but does not seem to find a graphics driver. The current driver in my working windows 10 version 1607 is 15.201.1001-150721a-187556C-Acer. Is there a problem with this driver and windows 10 creator? If so, is there another driver version that is compatible with Win 10 creator?
Your desktop PC has a legacy (Old Non-Supported) AMD GPU card in it. The last known driver for this card posted by AMD Support is here: Legacy
If you have the latest Windows 10 version, make sure it is totally updated via Windows Update. Uninstall the current driver using Windows Control Panel - Uninstall and then download and run DDU (Display Driver Uninstall) in safe mode. After rebooting install the last Full set AMD driver from the link above. See if Windows recognizes your GPU card.
