How to Copy USB to USB in Windows 10 Easily
Here I will use Windows 10 computer as an example and show you how to clone USB to USB with screenshots. The same steps also apply to cloning a USB bootable drive.
Step 1. Connect the two USB drives for copying.
Insert the source USB drive, and then the target one to your PC via USB ports.
Make sure they can both be detected by Windows.
Step 2. Launch the effective tool to copy USB drive.
Install and launch AOMEI Backupper, then go to Clone tab and select Disk Clone.
Step 3. Select the source USB and the target one.
Specify the source USB to copy, and then the other one as the destination. Don’t mix them up, or you’ll lose everything on the USB.
Step 4. Start copying USB to USB.
Here is the operation summary. You can also make an exact copy of the source USB by checking Sector By Sector Clone. Then click Start Clone to execute the operation.
You can take advantage of the "Edit Partitions" feature to fully utilize the disk space after cloning. Here are the options:
👉 Copy without resizing partitions: No changes will be made to the partition sizes on the new disk.
👉 Add unused space to all partitions: Spread any unallocated space across all partitions on the target disk automatically.
👉 Manually adjust partition size: Customize the size of any partition on the destination disk to suit your needs.
👉 Convert the destination disk from MBR/GPT to GPT/MBR: Change the partition style of the target disk to match that of the source drive (either MBR or GPT).
Wait for the process to complete. Click Finish when it is done and close the program.
👉 Useful Tips:
· These instructions work for USB-to-USB copying across different versions of Windows, including Windows 11, Windows 8, and Windows 7.
· If you select the "Sector By Sector Clone" option, the "Edit Partitions" feature will be disabled.
· AOMEI Backupper supports cloning various disk types, such as cloning HDD to Seagate SSD, cloning HDD to Samsung SSD, and even cloning NVMe to another NVMe drive.
Another Way to Copy USB Drive with Boot Files
In addition to the AOMEI Backupper, you can also use the command prompt to make a USB drive bootable, then extract the ISO image file via File Explorer or another ISO burner.
✎Note: If your USB drive is showing as a Removable Disk in Windows Explorer, you can only create one primary partition there. If it shows as a Fixed Disk, you can create multiple primary partitions in accordance with its size.
1. Connect a USB drive and Run Command Prompt as administrator. Click Start, type cmd in the search box, then select it from the search result list and run as administrator.
2. In the pop-up command prompt window, type the following syntax and hit Enter after each one.
- list disk
- select disk X (X stands for the drive letter or disk number of your USB drive)
- clean
- create part pri
- select partition 1 (This is the partition you just created)
- assign letter=N
- select partiion N
- format fs=ntfs quick (If you want to create UEFI bootable USB in diskpart, format it as FAT32. Type format fs=fat32 quick as instead)
- active
- exit
3. In Windows 8/10, right-click the ISO file and select Burn Disc Image, then follow the on-screen instructions to finish the rest of steps. In Windows 7, you could consider using a ISO burner as instead.
4. After that, restart your computer, press F2 or ESC to enter the BIOS screen, select the Boot tab, and use “+” to move the flash drive to the first place, then press F10 to save the changes. Later, it will go to the Windows Setup screen automatically. If not, the drive is not bootable or something goes wrong.
