After finding the way to access two disks on my ASUS laptop (the hardest of manipulation), I replaced the system drive with a SSD of 256 G and clone the system with the PARAGON Software software. The second hard drive was only 500 G, I substituted model. Installation without problem. Note: Premium delivery is no longer in a month on the day indicated, but with a delay of at least one day. I preferred delivery in relay with a day late, which saved me to wait for the passage of random delivery.
