Tip:This tutorial also applies to similar demands of copying OS from a laptop HDD/SSD to a USB pen drive. For example:
how to transfer Windows OS from a laptop to USB drive and make it bootable?
How to install the laptop OS on an external pen drive?

Since this example was a backup of OS X, it should be tested to confirm that the computer can be booted from it. Insert the drive and power down the computer. Hold the Option key and push the power button to boot the computer. Any bootable drives connected to the Mac should appear with their icons. Select the USB drive you just made.

The first backup may take a long time, depending on how many files you have, but you can continue using your Mac while a backup is underway.Time Machine backs up only the files that changed since the previous backup, so future.
Why Do You Copy OS from Your Laptop to a USB Pen Drive
Portable and accessible anywhere. For example, you can easily access your work computer system from home with only a USB drive!
- Then you can select the system drive to be backed up and the destination drive that could be internal or external hard drive. To backup OS to external hard drive, you should connect the external disk to the computer first and confirm that it can be recognized. Backup OS now Finally, click 'Start Backup' to begin the OS backup process.
- It makes backup OS to USB drive as easy as backup to other hard drives. This solution supports almost all removable USB drive (USB 1.0/2.0/3.0), thumb drive, pen drive etc. Backup for once or for long run depends on your requirements. Its incremental backup and differential backup will save much USB.
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!

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.
