[Q] My system, my 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 the 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 in CWM but its not much help since my other loads are still unmounted in TWRP and won't mount
