“I have a Windows 10 based Dell computer with UEFI boot mode. Now I want to create Windows 10 bootable USB and manage to boot my computer from it. Nevertheless, I don’t know what I should do? Is there anyone can give me detailed tutorial on making UEFI boot USB of Windows 10?”

Create UEFI bootable USB of Windows 10 via Diskpart

The first way to create Windows 10 bootable USB stick with supporting UEFI boot mode is to use Diskpart utility. Detailed steps are given below:

✎ Notices: Before the operation, you should prepare an ISO file; all data on the USB drive will be erased, you can backup files at first if you don’t want to lose them.

Step1. Insert your USB to the Windows 10 computer and ensure that it can be detected.

Step 2. Run Diskpart as administrator. Press Windows +R at the same time, input diskpart and hit Enter key.

Step 3. In Diskpart interface, run commands as follows:

▪ list disk
▪ select disk n
▪ clean
▪ create partition primary
▪ format fs=fat32 quick
▪ assign letter =x
▪ active
▪ exit


  • “n” refers to disk number of your USB drive; x is one of the available drive letters that can be assigned to the partition.

  • If you want to create Legacy bootable USB drive, replace format fs=fat32 with format fs=ntfs.

Step 4. Place your prepared custom image onto the root of the USB flash drive and if the USB drive is showing as Removable Disk in File Explorer, only one primary partition can be created on it.

After creating Legacy or UEFI boot USB drive of Windows 10 via Diskpart utility, you can insert the USB to the computer that you need to install operating system and boot from the USB drive to perform Windows installation.
