Step 4: Repeat step 1 and 2. But this time click ‘Enable’ in the ‘Intel HD (R) Graphics’ menu.
Step 5: Restart your computer. (A restart is essential so that all the changes are made properly, without any incomplete updates. You might skip this step, but it is strongly recommended that you should perform a restart.)
