Hello,
The Lenovo G450 is quite compatible for Windows 7, there could be following reasons:-
1. The CD/DVD Drive may not catch the CD/DVD becuase of lens may gone dusty, clean the lens. 2. DVD/CD may be damaged due to scratches, try another CD/DVD 3. Check the Boot options from BIOS, it must be CD/DVD on first boot
Good luck, and do rate the solution if got help

The reason may be one or more problems acting together. The problem nowadays is that it is very difficult and time consuming to monitor and take care of your Lenovo PC. Even experienced users find it hard to perform such tasks on regular basis because you might need to prepare a huge amount of time and energy to deal with each issue separately.

If you want to fix the problems more efficiently, try the Lenovo speed up program, available here: http://www.speeduplenovo.com/

Cheers!
