The installation of Windows 7 can be an adventure.
I am not a fan of pre-installed equipment, these recovery partitions are not my best friends, but they take a useless space.
For years, is my first approach: backup the entire hard drive, delete hard disk, repartition and install Windows fresh and without "bloatware" (Advertising).
Who is 5 530U3CA01 going exactly in this Samsung Series certainly notice that the device strictly speaking 2 hard disks. A conventional 500GB drive and a 24GB Express Cache. Who is this 24GB Express Cache also deletes then associated problems with it to install Windows because the EC is drive 0!
This is likely to bring for some users considerable problems! In forums this issue is often discussed.
So do not forget backup (sector by sector; for example with Acronis!) Start and only then with the new installation!
The device itself like it very much. A star deduction for the unfriendly Windows installation!
