How to partition a hard drive from Windows 10 without losing data?

I have also recently studied how to partition safely on Windows 10, especially to avoid the trouble of losing files. Here are two simple methods for you to easily partition a hard drive for Windows 10, and the files will not be lost.

Solution 1: Use the built-in disk management tool
Backup first: This is very important! Whether you use an external hard drive or cloud storage, back up important files first. External hard drives are reliable, and cloud storage is convenient. You can choose which one is more convenient.

1. Open Disk Management: Right-click "This PC", click "Manage", and then select "Disk Management".
2. Compress Volume: Find your primary partition (usually the C drive), right-click "Compress Volume", and enter the size of the space you want to divide.
3. Create a new partition: The compressed space will be displayed as "Unallocated", right-click it, select "New Simple Volume", and then follow the prompts to set the partition format and drive letter.
4. Complete the partition: It will be done in a few minutes, and there is no need to worry about file loss.

Solution 2: Use the command line (suitable for those who like to tinker)
Open the command prompt (administrator mode): press Win+S to search for "cmd", right-click and "Run as administrator".

1. Enter diskpart to enter the partition tool.
2. Enter list volume to view all partitions.
3. Select the partition you want to adjust: select volume X (X is the partition number).
4. Compress the partition: use the command shrink desired=XXXX (XXXX is the number of MB you want to allocate).
5. Create a new partition: enter create partition primary, then format: format fs=ntfs quick.
6. Assign a drive letter: assign letter=Y (Y is the drive letter you want to use).
7. Done! This can also be operated without pressure on partition a hard drive from Windows 10.

Reminder:
Pay attention to backup: disk operations are risky, and backup is double insurance.
Don't touch too many system disks: especially the C drive, be careful to allocate key system files.
Tool recommendation: If you are afraid of making mistakes using the command line, software like AMEI Partition Assistant is also super friendly.

I wish you a smooth partition and a perfect partition a hard drive from Windows 10!
