Too much of wind noise in cabin and grinding noise on start up

[Neesh]

Lately my cabins been very noisy because of wind noise how can I insulate the car to stop this?

Also when I start my car,as soon as I turn the key theres like a grinding noise for about a second and then it stops what is this?it doesnt happen on every start up but happens most of the time,should I be worried about anything?

The grinding noise sounds like a starter motor sticking. To fix, you need to replace it.
