The benefits of creating Windows 10 bootable USB

With the innovation of technology and the constant update of Windows operating system, you won’t be running the same version of OS on the same device forever, which also brings the demand for portable bootable media. For instance, you may want to copy Windows 10 to USB as a bootable drive, and use it for following purposes:

  • Clean install Windows 10 on new hardware or computer.

  • Upgrade earlier system to the latest version, like from Windows 7 to Windows 10.

  • Boot crashed computer into Windows 10 recovery environment for troubleshooting.

So what is the superiority of bootable USB over other media? Well, the obvious reason is that it’s the lightest and most portable one. Meanwhile, it can be used on a variety of devices, including thin laptops without optical drives.

In this post, I’ll introduces 3 methods to copy Windows to USB for free.

How can you copy Windows 10 to make bootable USB?

Windows 10 comes with Backup and Restore utility to backup files, volumes or OS, but system files backed up in this way can only be stored as data. If you want to use the USB as a bootable drive, there are some other approaches you can take, and the results of them are functionally different.

Installation USB: Copy Windows 10 ISO to USB and therefore creating a bootable drive. It could be used to clean install Windows 10 from USB on the same or another computer.

Recovery USB: It contains all the advanced recovery options to help you troubleshoot Windows 10 even when the computer won’t boot. If you back up system files to the USB, you can also use it to reinstall Windows 10. Note it usually doesn’t apply to different computer.

Bootable USB: There are many software can create bootable USB or other media, just pick the one that best suits your needs. Here I’ll use Create Bootable Media tool of AOMEI Backupper as an example. It enables you to boot a crashed computer into WinPE and restore Windows 10 to an earlier state. You can even add a boot option to perform system recovery without any media.

1. Copy Windows 10 to USB for upgrading or clean Installing

Preparations:
☛ To copy Windows 10 installation to USB, you need to download MediaCreationTool first. Find “Create Windows 10 installation media” and click "Download tool now" below it.
☛ Prepare a USB flash drive with at least 8 GB. If it’s not empty, the data stored in it will be erased, then it’s better to make a backup in advance.
☛ You’ll need your 25-character product key to activate Windows.

How to copy Windows setup to the USB flash drive:

1. Open the MediaCreationTool. If you want to upgrade or reinstall the current computer right away, just choose Upgrade this PC now, otherwise please choose Create installation media for another PC and click Next.

2. Select the configurations of the Windows 10 ISO you will download. If you want to use the USB on the same computer, just let it Use the recommended options for this PC, otherwise please uncheck it to make your choices according to actual situation.

If you are not sure what’s your architecture (32-bit or 64-bit), check it in Control Panel > System > System type.

Select Language Edition

3. Choose USB flash drive and click Next to copy Windows 10 ISO to USB. You can then use it to boot and (re)install the same or another computer.

Select Media

To install Windows 10 from USB, just connect it to the computer with corresponding configurations, enter BIOS to set the USB as the first place in boot order, then choose language and keyboard layout. You will be required to enter the product key, you can register it now or later. Then, just follow the wizard to clean install Windows 10.

2. Copy Windows 10 to USB for troubleshooting or reinstallation

Preparations:
☛ You need a USB drive with at least 16 gigabytes space to create a recovery drive.
☛ The USB better be empty, otherwise the data in it will be erased. Sure, you could also backup files on USB at first.
☛ Connect the USB to your computer.

Then, you can either select Advanced options to troubleshoot Windows 10 with Startup Repair, System Restore, System Image Recovery, Safe Mode, Command Line, etc., or select Recover from a USB to reinstall Windows and decide whether to remove personal files or fully clean the drive.

3. Easier & safer way to create bootable USB and repair Windows 10

A bootable USB can be used for different purposes, but simply put: repair windows 10, install/reinstall Windows 10.

The easiest way to repair Windows 10 is to restore it to an normal state, which could be perfectly implemented by system backup and restore feature of AOMEI Backupper. You can also create bootable USB or boot option to recover a crashed computer in WinPE - it’s kind of like System Image Recovery in Windows but much easier.

As for installing, normally a clean install shouldn’t erase your files, but there are still chances of data loss, and the reinstalling from USB is clearly said to remove your files. In this case, AOMEI Backupper could provide an effective precaution to backup important files, partitions, system or the entire disk before reinstalling.

In addition, if you don't insist on clean install and just want to move windows 10 installation to a new HDD or SSD, you can directly clone or image Windows 10 to new hard drive without reinstallation. The Universal Restore feature (available in advanced editions) also allows you to restore system to another computer with different hardware. Thus you don’t have to install and configure system from scratch.

You can download the free standard edition to have a try. It already contains most of the features you need, like system backup & restore and creating bootable USB.

Conclusion

But for better system protection and simpler operation, AOMEI Backupper is also a good choice. You can auto backup operating system with it and use bootable USB to recover the faulty computer whenever you need.

If you are planning to move Windows 10 to new hard drive rather than clean install, this software also enables you to migrate OS, like transferring Windows from HDD to SSD.

If you prefer to onekey backup system and perform a quick restore without USB or any other media, you could also try AOMEI OneKey Recovery.
