Portable and accessible anywhere. For example, you can easily access your work computer system from home with only a USB drive!
That fully explains why you put a laptop OS on a removable storage device. In fact, other than carrying your laptop operating system elsewhere (at home, in the office or on a business trip), there is another noticeable benefit. With a bootable USB pen drive at hand, you shall feel worry-free and risk-free when accidents happen, especially the hardware failure or system blue/black screen of death that prevents you from booting up your laptop normally.
What's the Best Way to Put Your Laptop OS to a USB Pen Drive
First, let's list some viable solutions:
- Windows To Go Creator.
- System backup software.
- System clone software.

As we know that the Windows To Go is a feature only available in Windows 8.1 Enterprise, Windows 8 Enterprise, Windows 10 Enterprise and Windows 10 Education. People running those mentioned operating system editions can use this tool to install OS on some supported USB drives. Otherwise, it's likely to receive the error 'this is a removable drive and isn't compatible with Windows To Go' and fail to create Windows To Go with non-certified USB flash drive.
By contrast, the latter two ways seem to be much easier with fewer limitations. Even though, the last way of system clone is much better!
This is what you should clearly understand between the two manners of copying OS from a laptop HDD/SSD to a USB pen drive.
First, you need to download EaseUS Todo Backup on your laptop. It's reputable Windows backup software with comprehensive solutions to system backup and system clone.
Second, the system backup way takes effect like this:
It's software associated. i.e., you can only use the software to back up the laptop operating system, in addition, restore the system from the USB pen drive via the software again.

At last, the system clone way is the simplest and most efficient. It's independently existed as long as you have transferred the operating system from the laptop to the USB drive, which means that once the bootable USB pen drive is successfully made for the first time, you can boot the laptop OS anytime on any other computer or laptop, without requiring additional tools!
How to Create a Portable USB Pen Drive with Easeus Todo Backup
USB requirements:
1. Check how much disk space is used for the system C drive. Let's assume 40GB. Then prepare a qualified USB drive, of which the disk capacity must be larger than 40GB.
2. Do you use an empty new USB drive or an old one? Make sure that all the important data has been safely transferred because the system clone will overwrite data on it completely.
3. Correctly connect the USB drive to your machine and make sure that Windows has detected it and assigned a drive letter to it.
Follow the overall process to create a portable Windows USB drive and boot from it:
Step 1. Launch EaseUS Todo Backup. Expand the menu and click 'System Clone' in the lower position.
Step 2. On the 'System clone' window, the software will choose the system partition and boot partition by default. Just Choose the USB drive as the destination disk.
Click on 'Advanced options' and then 'Create Portable Windows USB drive'. Click 'OK'.
Click 'Proceed'. The software will start immediately cloning the default partitions of your desktop/laptop to the USB drive. After the cloning process is over, you can safely plug the USB drive out.
