Inspiron 17 (7737, Mid 2013) INSTALL Driver Win7 + Ubuntu

I want to install Windows 7 and Ubuntu . . .
The drivers you can get from Dell are only for Win8.

Who can help and give some advises for this problem !
From my opinion for the components inside there must be a driver support for win7 and / or linux.

Have someone a idea how to handle this ? + !
