If I format HDD and install Windows 7, will my wireless adapter driver be deleted?

I have a Lenovo Y50. It came with Windows 8.1, and it's a real nightmare. I have a Windows 7 Ultimate CD here, and here's my question… If I format the drive and install Windows 7, what will become of all my drivers? The only driver I'm super concerned with is the internal wireless adapter's. Anything past that, I can just find online. So will it be deleted, or will my computer somehow keep that?

All your drivers that you've installed since you got your computer will be deleted.

Formatting your hard drive means it deletes EVERYTHING off your hard drive.

If you install a generic copy of Windows 7, all of the drivers will be erased.

Yes it will delete the drivers but it should reinstall them when you hook it up in win 7
