Unlike this question, I have 5 already-formatted partitions (Each are "Logical" and "N.T.F.S" style) in the hard disk, and all are being used for specific type of documents. (C drive being used for Windows)
I want to install Linux Ubuntu for desktop on the pre-existing drive D; and without interfering any pre-existing partitions and their contents. I have downloaded the ISO file. Please guide me with flow charts.
