Clean install of windows 8.1 on new Lenovo Z50

[theproman23]

I just purchased a Lenovo Z50-70 and want to remove the bloatware and perform a clean install. I was able to retrieve the product key using a key finder software but can't figure out how to go about performing this clean install.

I've downloaded a windows 8.1 ISO and put it on both a DVD and a USB flash drive and trying booting to both but I keep getting some message about cable being disconnected and it doesn't seem to process through.

The version of windows 8.1 is OEM 64-bit.

Any help you guys can provide would be great!!!
