I just bought a laptop with some pre-setup partitions like recovery partition, OEM partition, a smaller Windows-partition and the Windows system partition. Their structure and size looks like this:
I don't really like this 650 GB partition for the system... and thought about resizing this partition for a max. 60 GB partition (that should be enough for the Windows-partition), and leaving the rest for my own other data (music, films, etc.) with a program like GParted or anything similar... I don't really want to remove factory partitions, rebuild the whole partition system and reinstall Windows.
Some say it's not a really good practice to resize or restructure any partition after an OS is installed onto it.
Let's assume resizing happens without a problem (I think it should with a program like GParted), and the OS is running.
Is there any problem with that approach? Can it cause any kind of problems?
There may be things I didn't think of.
