Comment 3 for bug 543891

Ok, thanks for the explanation. I tried the "custom partitioning" option, but it was not at all obvious to me how to use it to make it overwrite and reuse the existing Linux (1). How about providing a clear reinstallation option within custom partitioning or after it?

Also, could you answer my question in step 9 about the leftover empty partition? Why is there the empty partition in the extended partition? It causes no harm but it's unnecessary and untidy, and I'd like to know what is the Mint-recommended way of removing it.
