I would like to split this large C: partition into two partitions, leaving only 100 GiB for the system, and giving the rest to a new data partition.Īlthough the Windows built-in Disk Management utility has an option to shrink the bootable partition, it only allows me to shrink it roughly by half, even though only 20 GiB on the partition is used. It has a 500 GB HDD with three partitions: a small hidden system partition, a 12 GiB HP recovery partition, and a 450 GiB C: boot partition. I have just bought an HP laptop with Windows 7 (64 bit).
