Way 2: Copy partition to another drive using command prompt

If you wonder if there is a built-in tool or method in Windows 10 that allows you to copy a partition to another drive, the answer is to use the xcopy command. Follow the steps below.

Step 1: Make sure you have signed in to Windows 10 as an account with administrator rights. Type cmd in the Cortana search box. When the Command Prompt shortcut appears in the search results, right-click it and select Run as administrator.

Step 2: In the Command Prompt window that opens, type xcopy d:\ e:\ /s /e /h /I /c /y and press Enter. Replace d:\ with the drive letter of the partition you want to copy, and replace e:\ with the drive letter of another drive you want to use as the destination partition.

Step 3: Command Prompt will start copying all the files and subdirectories (including any empty subdirectories, any system or hidden files) on the source partition to the destination partition or drive. Wait for the coping process to complete. This takes a few minutes, depending on how much data to be copied. But in any case, it will much faster than manually copying and pasting files. Do not close the Command Prompt window until the copy is finished.

Tips: The xcopy command helps you copy a partition quickly and accurately. However, it is mainly applicable when the data stored in the partition is ordinary files, such as photos, videos, PDF, ZIP, and other documents. It’s not recommended to use the xcopy command to copy system boot partitions or partitions containing installed software programs. Because the operating system and software programs copied through the Command Prompt may not start properly on the new drive.
