You don't need to root it to boot a custom rom--rooting only affects user-land after you have booted.
What you need to do is unlock your bootloader. > fastboot oem unlock or > fastboot flashing unlock see: http://www.howtogeek.com/239798/how-to-unlock-your-android-phones-bootloader-the-official-way/ Without that, you won't be able to boot a custom rom because the bootloader doesn't see a system image that passes its tests.
