According to your description, you want to merge the EFI partition and NTFS partition on your USB flash drive, which is a tough mission since your EFI partition contains the Windows system. To securely combine the two partitions on your USB, I recommend you try EaseUS Partition Master. This versatile and practical partition manager software can help you merge multiple partitions within three steps.

Option 1. Combine All Partitions 

If the EFI and NTFS partitions you want to combine are adjacent, EaseUS Partition Master's "Merge" function can apply to this situation. Detailed steps are here:

Step 1. Right-click on the EFI partition and choose "Merge."

Step 2. Locate the NTFS partition to merge, and click "OK" to ensure the warning.

Step 3. Click the "Execute Task" and "Apply" in the window.

This merge program will combine space and move files from the NTFS partition to the EFI partition.

Option 2. Delete All Partitions

If the data on your USB is unnecessary or you already backed up the data, you can delete all the existing data using Disk Management.

Note: This process will erase all the data on your USB, which requires you to copy the data in advance.

Step 1. Press "Windows + X" > "Disk Management".

Step 2. Right-click the NTFS partition and choose "Delete Volume". In the pop-up window, click "Yes".

Step 3. Repeat this procedure to delete the EFI partition.
