Buy a second disk drive, put it in, and install Linux on that drive, leaving your existing drive completely alone.
Initially, when starting-up Linux, you should designate the new drive as your startup drive in the BIOS "setup" screen. The BIOS should be told to ignore the Windows drive for booting purposes.
Now... with no further ado... you have a way to switch from Windows to Linux and back again, by changing the BIOS Setup. It's not the only way of course, but it will put you in the position you need to be in: viz, you can reliably switch from one OS to the other at-will, and you can experiment with Linux while making no changes whatever to Windows.
Use a Linux distro of very recent vintage. It will probably recognize your wireless hardware right out of the box. But now you always have a fall-back position. You can always get back to a known position, and you can always make your forays into Linux with safe experimentation.
