Different people have different needs and it is way not polite to call someone an idiot just because he is not like you.
For example - me and almost all my friends and also some members of this forum don't understand why no to move all your documents/media/games to drive "D" ? It's done for the safety of your data in case of OS fail - you just recover OS and all your data is safe on "D".
And what are YOU going to do?
You're resizing "C", which affects built-in recovery function and when something happens (as practice and time shows) you lose all your data (if you don't know how to resize partition I'm sure you aparently don't how to recover all deleted data - I know all this and helped many people, so be sure I know what's the point) and cry out "Oh Lenovo Idiots, oh they broke my life, oh their notebooks are useless and stupid".
Regarding topic:
Perhaps you should delete all partitions (D, Recovery) except "C:" and expand your partition to the hole size of HDD - this space must be enough. Resizing "C" makes restore partition useless and you can free up 18-22 gb by deleting it.
