TWRP: No OS installed. Device stuck on logo screen when booted.

Hi, I've been trying to install android M 6.0 through TWRP, and somehow deleted the OS from my system. Now whenever I boot my device (Huawei P8-lite dual sim) it gets stuck on the Huawei-logo screen. I can get into fast boot& rescue mode and I can get into TWRP, but I don't know how to repair my phone from there.
