How to install a software to the newer os which I have it preinstalled in the older os in the same pc?

I have a lenovo pc which came with win 7 preinstalled. It had those dolby advanced audio, intel graphics 3000 and stuff preloaded. Today I installed win 8.1 to the same pc but on the separate disk partition as to retain the older os win 7. But when I run my pc through win 8 the video lacks clarity. I believe its bcoz it doesn't have that intel graphics 3000 as in win 7. So you guys please help me how to copy and install those dolby and intel stuffs from win 7 to win 8… Thank you

Wipe the lot - have one partition - go to win 10 - do a custom install - update all the drivers using drivereasy

Have you checked Lenovo's website to see if they have Windows 8 drivers to download and install? That would be the easiest way. If there are no Windows 8 drivers, you might be able to use the Windows 7 drivers, but BACKUP YOUR COMPUTER FIRST.
