The problem was that, after performing the shrinking, I could reduce the size only to ~460GB (not enough for my purposes).
To upgrade to a SSD drive, follow this step by step tutorial by following this link: HW – Upgrade laptop with an SSD drive Problem / Error So, given that the C: (system) partition has only 30 GB used (~896 GB of total size), one of the first configurations I wanted to do with my new laptop was shrinking this partition to 120 GB. I would like (maybe very shortly) to move the system and applications to a new SSD drive (perhaps 120GB or 240GB size).
