No os on galaxy tab2 gt5110 wont boot stuck on twrp after kingroot file error

No os on galaxy tab2 gt5110 wont boot stuck on twrp after kingroot file error. I tried to remove root, did a factory reset and now all I get is tarp recovery and the galaxy tab 2 start screen but does nothing. I've been through all the categories on twrp but keeps saying " No os installed , reboot anyway" . Been trying for hrs, anger building, please help..
