Regarding the partitions: my understanding is that those numbers you point out should be evenly divisible by 4. Both are. Both are also evenly divisible by 4096, but I am not sure that divisibility by 4096 matters.
Regarding the install, I would have done this:
Disconnect all peripherals and any hard drive not to receive Windows.
Then install to the SSD using a Windows disk, not an Asus disk.
Then inspect functionality by testing functions directly and looking in Device Manager.
If I lacked functionality or saw any errors in Device Manager, I would look for drivers
. Otherwise, I would not look for drivers.
If I had to look for drivers, my first source would likely be the Asus web site, not an Asus disc. Failing that, I might look at other hardware manufacturer's sites---Intel, printer maker, etc.
I would not use any type of Asus disc for any purpose, other than in desperation.
