Create Bootable USB from Android without PC: How to Guide

Want to create a bootable USB from an android device?

If yes, then this post is definitely for you.

Creating a bootable USB flash drive using a PC is easy.

But what if your PC is not working & you don’t have another machine.

Then it sounds a little difficult to create it. But don’t worry I have a solution.

Last week, my windows 10 got crashed/corrupted.

And to do a clean install, I badly need a bootable USB stick.

But for that, I need to create it first without using my PC.

And then I realized that creating a bootable USB drive using an android phone can be a good option.

Let’s see how it works…

How to Create Bootable USB from Android without using PC

But before we begin.

Please make sure that you have all the things mentioned in the given below list.

  • An android smartphone. (Of course, you already have it)
  • 4/8Gb Pendrive. (To create bootable USB disks)
  • An OTG Cable Connector (For connecting USB to your android device)
  • ISO image file of your desired Operating system. (Like Windows 10,7 etc.)
  • And the most important thing ISO 2 USB android app.

And to download the Windows 10 ISO file you can click on the given link.

What is ISO 2 USB [No Root]?

ISO 2 USB is an android app which allows you to convert ISO to USB using your android phone. It can also be called as Rufus for Android, using which you can easily create your bootable USB for Windows & Linux OS without using PC. And the best part of this app is that it also works with the No Root / Non-Rooted  Android devices.

Now I hope you have all the above-mentioned things with you.

So, Let’s get started with this step by step guide.

1. Install ISO 2 USB App

Now open your Android phone, then Go to Play Store and search for ISO 2 USB [No Root]Otherwise, you can simply click on this link and install it properly.

And after that…

2. Connect USB to Android

Once the ISO 2 USB app is installed, then connect your USB flash drive to your Android phone using OTG Cable Connector.

Note:- Please make sure that your Android mobile phone or your Android Operating System supports OTG Cable Connection properly.

 3. Open ISO 2 USB App

Now open ISO 2 USB application to make your bootable USB and check the USB is connected properly or not. For that, you can check your File manager where you can see your USB device connected.

Now comes the major part of creating a bootable USB from an android device.

4. Pick USB Drive & ISO File

Now you can see that there are two options available there. The first one is “Pick USB Pin Drive” and the other one “Pick ISO File”. So first select the USB drive by clicking on the “Pick” button and then tap on the USB drive which you have connected earlier.

After selecting the USB drive, now select the Windows 10 ISO file by clicking on the “Pick” button in front of the “Pick ISO File” option. Then browse to the mobile storage where you have downloaded the ISO file earlier and then select or enable the checkbox & Click OK.

5. Create a bootable USB using Android

Now the ISO file and USB drive have been selected. But before converting ISO to bootable USB, you first need to create a clean partition and format the USB drive. So, Enable the USB “Format USB Driver” checkbox and then at last Click on the “START” button.

Once the bootable creation has started, now wait for 10-15 minutes and your bootable device will be ready. At this time of the process, you may see multiple ads on the screen which you have to close them and keep continuing the process.

Finally, when the burning ISO file is done successfully, it will show a message 100% Done and the USB Device Removed. Which means you have successfully created a bootable USB drive.

And your windows 10 installer is ready to install on your PC.

Note:- Before starting this process, please make sure your Phone is 70-80% is charged and you are connected to the internet till the end of the process.

    • Hi,

      I think this is happening because the USB drive with a FAT32 file system doesn’t support files larger than 4Gb. So I would suggest you please first convert the USB drive file system from FAT32 to NTFS. And then use this app for creating a bootable USB drive.


    • Use NTFS system type usb to do that go to pc right click on your usb drive select format now select NTFS not choosing the default system type fat32 and click format

  1. Wow, another nerd technique to impress my friends with! Their Windows crashed and my only working laptop was also down, so I’ve booted Windows to my pendrive using this guide. Now to go and show them some magic, thanks again!

    • Hello Deepesh,

      Yes! I agree with you and this error is coming because of the different USB File Systems. So I would suggest you to change your USB file system to FAT32 (which is the default USB file system).
      Thanks 🙂
