Dear Experts,

Recently I am facing lot of problem with Ubuntu OS 16lts. In one year I have formatted 4 times because of nvidia graphic card driver issue (happens after update) or some unknown reason ( I am not tech tech guy to figure out all the problem). Yesterday onwards problem started again. I couldn't open ubuntu. Initially it was blank screen, after following some suggestion from forum I removed nvidia driver and tried lot other things. Still not functioning. Therefore I am planning to go for cent os. 

After installing cent os should I redo all analysis again? or I can continue with whatever so far done by using Ubuntu os?   

Thanks
