Creating a bootable USB to install Windows is one of the many ways to make a choice, with a fast installation speed and a small device. Currently there are many USB boot software to choose from. And after creating the user should also check the performance of USB boot, whether created successfully or not. Instead of having to turn off the computer and plug in the USB to check, users can use some software to check the USB boot after creating. The following article will guide you how to check USB boot on Windows.

1. Check USB boot with Ultimate Boot USB


After downloading the tool, the user also runs under Admin Admin, right-click on the installation file and select Run as administrator . In the UltimateBootUSB interface at the Drive Letter section you choose to USB drive, then press USB Test .

2. USB boot test with QemuBootTester


QemuBootTester also requires users to start using Admin rights. At the interface click Hard Disk to check the performance of USB boot or hard drive. Below select the USB drive name and press Run Qemu . This is the case for users who boot standard USB Legacy .

3. Use Qemu Simple Boot software


This is a completely free program, provided as a compressed file, all you need to do is download it to your computer, extract and run the file Qsib.exe:

Run Qemu Simple Boot

The main interface of the Qemu Simple Boot program will look like the image below, you just need to pay attention to some information as follows:

  • At the Bootable part, we will choose the HDD.
  • The Ram Size section pushes up to full size, 1024 MB corresponding to 1 GB of RAM memory.
  • In the Select Physical Disk section, you will select the USB drive, as the example here is drive I.
  • Finally, click the Start Qemu Test button.

If successful, the boot screen of the USB will be similar to when you booted outside the real machine, except for 1 point is good level of boot through the emulator will not be as fast as the real machine.

4. Use MobaLiveCD

Another easy way to check if the USB Boot has been successfully created is MobaLiveCD software. This is software that simulates Qemu system. It will run an ad-hoc virtual machine and boot from USB, so this is a great way to check the USB boot status.

Download MobaLiveCD from the developer website according to the link below.

After completing the download process, right-click on the downloaded EXE and select "Run as Administrator" . If you do not run the program as an admin, you will get the error "Setup cannot copy the kqemu.sys file"  and you will not be able to proceed to the fifth step.

Run MobaLive CD as admin

Click the "Run the LiveUSB" button in the bottom half of the window.

Select Run the LiveUSB

Select the USB you want to check from the drop down menu. If you are unsure of the drive letter, check the Explorer window and locate the drive in the sidebar.

Select OK

When asked to create a hard disk for the virtual machine, click " No " next to the red X.

Select No

Next, you will see the Command Prompt appear with the boot boot text line. This means that the virtual machine is trying to boot from the drive you selected in the previous step.

If you see the Windows logo, this means the drive can boot. Click the X in the upper right to close the window.

If this process freezes or crashes at the command window, your drive cannot boot.

5. Magic ISO Maker checks the disk image file

You can also use the free "ancient" Magic ISO Maker software to see if the drive image file can boot. This is a good way to make sure the drive image file is bootable before you burn it to USB.

Download Magic ISO Maker . If you have been using computers since the 19th century, it will remind you of the ancient full-screen installer.

After the installation process is complete, open Magic ISO Maker and select "Open ..."from the " File " menu .

Open ISO file

Select your ISO file from the menu.

Select the ISO file from the menu

Look in the menu bar. If you see " Bootable " it means that ISO will boot once it is written to a CD or USB disk. If "Bootable" is not found, it means that you have not created a USB Boot.

Appearing from Bootable means USB boot succeeded

The best way to check if a bootable drive is to boot the computer from the drive. But if you do not want to restart the computer, you can use Qemu Simple Boot or MobaLiveCD to check the drive. If you want to make sure that an iamge drive file (such as ISO or DMG) is bootable before burning it to a USB or CD, Magic ISO Maker is the perfect choice. 

I wish you all success!
