Alright, so the other day I installed Ubuntu GNOME alongside Windows 8. Now I've decided that the latest version is just too buggy, and I want to switch to stock Ubuntu.
Instead of just installing the Unity environment, I want to erase Ubuntu GNOME and restart fresh. I've messed a lot of stuff up with my graphics settings, installed LXDE to try to fix problems I was having, etc. It's just a mess and I want to restart.
How do I do this without messing up my system? Both Ubuntu and Windows are installed in UEFI mode.
Thanks!
