Firstly, you will need to find out which Wireless card is present in your tablet. Some cards aren't supported.
The next step is to download an install ISO file (e.g.
android-x86-4.4-RC1.iso) from the downloads section, and use the
dd command or unetbootin in Linux to copy it to a USB drive.
Then, simply choose the USB device from the BIOS and try it out on Live mode before installing to check that everything works!
If you want to keep Mint, you will need to partition the hard drive using gparted before installing Android though.
