The first time you have to do that download the ISO file from the operating system that will be used. In this practical, I will create an example to download a Windows 10 ISO file.

  • The first step, if you want to use Windows 10 as well then click Download ISO.
  • Then you click the Download tool now menu. Then it will automatically download the Media Creation Tool file.

Furthermore, after you have prepared the ISO file, it is time to practice making a bootable flash disk.

Then to make it very flexible, because you can use additional software or with the default features of the PC / Laptop used.

I will also practice several methods that you can choose later, so watch carefully.

# 1. Make Bootable With Rufus

In making a bootable flash disk, I highly recommend you to use the Rufus application.

Why? Because this application can be downloaded for free and is certainly very easy to use even for laymen.

Follow these steps to use the Rufus application to create a bootable flash disk :

  • After successfully downloading, now you open the Rufus application and connect the flash disk that will be made bootable.


If the flash has been detected, then you can see it in the Device menu.

  • Then select the ISO to be used by clicking the Boot selection menu > Click Select. Make sure the Partition scheme menu and the Target system are appropriate.
  • Now you Click Start. If you are confused, please look at the image below and adjust it to the points I have given.

# 2. Make a Bootable Flashdisk With Command Prompt

If you want to make a bootable flash disk without additional applications, then I recommend using the Command Prompt (CMD).

Even though the process takes a little longer than using Rufus, it’s just as easy. The difference is that with CMD you have to use certain commands.

If you want to know how, please follow these steps:

  • First, you have to open Windows then Type CMD or Command Prompt.
  • After CMD opens, Type Diskpart. Then the system will ask for Administrator access, you can click Yes. Then you will be redirected to the diskpart.exe window.

  • The next step is to create a partition from the cleaned disk. The trick, type create partition primary> select partition 1> active .

  • Now type the command format fs = fat32. In addition, you can also use the NTFS format by typing the format fs = NTFS.

  • Next, please wait until the formatting is complete, it usually takes more than 10 minutes.
  • When finished, you type Exit> Press Enter. Finally, you only have to copy the ISO file that was downloaded earlier into the flash.


Also, make sure all ISO files have been copied correctly so that there are no errors during the installation process.

Now you can try to install Windows or other operating systems onto your PC / laptop.

# 3. Using WinToFlash

Apart from using the Rufus application, you can also try WinToFlash to create a bootable flash disk. This application is also free, the size is a little bigger but really practical.

  • After that you select the option I Have image or archive (like ZIP, RAR, DMG, etc.) somewhere > Click Next. This option indicates that the source file to be used is in ISO format.
Using WinToFlash
  • In the Basic parameters window, there are 2 menus for you to fill. Fill in the Windows files path menu with the ISO that will be used. Then for the USB drive, select the flash drive that you want to make bootable.
Using WinToFlash
  • In the Ready to Start window, you can directly click Next.
Using WinToFlash
  • Next, in the Windows License Agreement, you must select the option I do accept the terms of the license agreement> Click Continue. Then the bootable process will take place.

  • Finally, you wait until the process is complete. If so, now your flashdisk can be used to install Windows on a PC / Laptop.

# 4. Using UNetbootin

There are many ways to make a bootable flash disk, including using the UNetbootin application.

Other Application Recommendations To Make Bootable on Flashdisk

Actually, there are still many other application recommendations that can be used to make a bootable flash disk.

If you want to know what the application is, please see some of the recommendations below:

  • WinSetupFromUSB
  • Lili
  • RMPrepUSB
  • Universal USB Installer

Check Hard Disk Type (MBR or GPT) To Install Bootable

After making a bootable flash drive, you should also know the type of hard drive partition of the PC / laptop used.

The reason is, if you choose the wrong hard drive partition during the process, there is a possibility that the bootable that has been made can’t be used.

Now the type of hard drive itself is divided into 2, namely:

  • MBR ( Master Boot Record )
  • GPT ( GUID Partition Table )

A little discussion, yes, the type of MBR hard drive is a component of legacy devices, while GPT is used on the latest PC / Laptop releases.

Then for the characteristics, usually PCs / Laptops that use the MBR hard drive type have storage, not more than 2GB. For the type of GPT hard drive, there is no storage limit.

To find out the type of hard disk partition on your PC / Laptop, please follow the following tutorial:

  • The first step, you have to open a Command Prompt. The trick is to click Windows> Type Command Prompt.
  • Next, you type diskpart> Enter. Then there will be a notification from the system warning that the order must be with Administrator permission. You click Yes, the diskpart.exe window will open.
Check Hard Disk Type (MBR or GPT) To Install Bootable
  1. After that you type list disk> Enter, using this command you can see all the disks that the PC / Laptop is currently using.
  2. Now to find out the type you can see the arrows I pointed out. So if your hard drive is a GPT ( GUID Partition Table ) type, there will be a star in the column.
Check Hard Disk Type (MBR or GPT) To Install Bootable

The Final Word

Well, now you can practice how to make Windows bootable on a flashdisk.

Then you can install it to a PC / laptop via the bootable flash disk.

I think that’s enough tutorial that I can provide, I hope this information is useful. Thanks.
