For Windows 8/8.1/10 machines, it's crucial not to partition disks in Windows PE. Instead, directly partition within Windows to avoid file path issues that may prevent the system from booting.
Utilize Shrink Volume software for quick and efficient disk partitioning directly within Windows:
- Download Shrink Volume >> here.
- Execute: open Shrink Volume.

The main interface of the program offers 3 options:
- Allocate Disk Space as Desired: The selected disk will have the specified GB capacity, with the remainder allocated as a separate partition.
Step 1: Allocate Partition with the desired capacity.

Step 2: Select Partition.

Step 3: Choose the disk.

Step 4: Input the desired partition size.

Step 5: Execute.

Example: Choose a 500 GB disk to partition, input a size of 100. You will then have a 100 GB partition and a 400 GB partition.
Note: It is essential to follow the instructions precisely.
- Automatically Divide HDD into 2 Partitions: Automatically split the disk into 2 partitions (see details below).
Step 1: Automatically divide HDD into 2 Partitions.

Step 2: Select Partition >> Execute.

Example: For a 500 GB disk, the software will allocate 80 GB, and the remaining space will be divided into 2 partitions, each with 210 GB.
- Automatically Divide HDD into 3 Partitions: This is the section you'll find most useful.
Step 1: Automatically divide HDD into 3 Partitions.
