[Q] My system,data, preload,internal storage or external storage won't mount topic

I accidentally formatted and unmounted my system on my N7000 in CWM v6 .0 .5 .0 but i can still access my external storage in installing a zip somehow. I recently successfully installed Lollipop beta 5.0.1 cyanogen based on my Note but then i wanted to go back to slim wizz rom because i missed that tablet feature . After re-installing the slimwizz tablet rom i accidentally formatted and unmounted my system and the slim wizz doesn't boot up. When i turn my phone on it boot loops from the lollipop animation and stays as such. Before i did the Slimwizz i used twrp - installed the kernel for slim wizz , rebooted and from CWM i flashed the Slimwizz then somehow while formatting cache, data and internal storage (cause i really didn't have anything in there anyways) i accidentally unmounted my system in process

What can be done to re-mount my system, various storages and data back? Also i can still access TWRP by installing the kernel zip from my sd card but its not much help since my loads are still unmounted in TWRP
