Step 2: Now we need to create a bootable USB drive. We have a guide for that, so make sure you follow it and move on to the next step: Create macOS Catalina Bootable USB Flash Drive Installer, Here’s How. Step 3: When you have your USB drive, turn your Mac off and insert it. Turn the Mac. Jun 26, 2019 A macOS Catalina USB install drive is a great tool to have on hand to for quick and easy macOS 10.15 reinstalls. We show you how in this video tutorial. Once the bootable USB key is created, restart your Mac, press and hold the Option key and select the USB key to boot from USB. Thereafter you can proceed to format and install macOS on Hard disk. Once macOS is installed, the last supported version of Xcode can be installed from Mac App Store.

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!
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.
Step 3. Boot from the USB drive.
- Connect your portable USB to the computer
- Restart the computer and press 'Del' to enter BIOS
- Set the PC to boot from the portable USB by changing the boot order in BIOS under the 'Boot' tab
- Save changes and you'll see your system booting up from the USB drive
Install Mac Os On Flash Drive
If you have more than one Mac you want to upgrade to macOS 10.15 Catalina but don't want to waste so much bandwidth downloading it for each machine, one option is to create a bootable installer on a spare USB flash drive. Here's how to do it with the Terminal.
One of the problems with the release of a major operating system update like macOS Catalina is the amount of times it has to be downloaded. As Apple usually intends each Mac or MacBook needing to be updated to download it, the process isn't really efficient enough for instances where many Mac desktops need the upgrade, like in a school or business if there isn't device management or macOS Content Caching for whatever the reason.
![Usb Usb](/uploads/1/2/6/6/126605575/497032745.png)
The strain could also be felt by users who own multiple Macs but also have a limited data allowance from their Internet provider, or a small amount of bandwidth that could make updating multiple machines take a very long time and saturate the available connection.
While in the olden days it was possible to get the software update on physical media, Apple doesn't offer that option anymore. However, it is still possible to create your own media, such as a spare USB thumb drive, that can do the same job.
The first hurdle is to actually get the macOS Catalina installer onto a Mac. This is an unavoidable part of the process and will require just over 8 gigabytes of drive capacity to store.
Go to the Mac App Store and search for Catalina using the search bar, then click on View next to the macOS Catalina listing. Alternately, open the Mac App Store Preview page for macOS Catalina here then select View in Mac App Store.
Click on Get. This will load up the Software Update utility, which will ask if you want to download macOS Catalina. Click Download.
After the download has finished, macOS will automatically start the installer. Press Command-Q to quit the installer before it continues, as the update will be deleted upon installation.
Creating the Bootable Drive
You need an external drive to turn into a bootable version, and since it needs to be portable, your best choice is a USB thumb drive with a capacity of 16GB or more. Be aware that the drive will be wiped as part of the process, so ensure there isn't any precious data on the drive that could be lost if it isn't backed up elsewhere.
Connect the external drive to your Mac, and make a note of the external drive's name as it appears within macOS. This is important, as using the wrong name could lead to another connected drive being wiped by mistake.
Open Terminal within the Utilities folder within the Applications folder and enter in the following command by copying and pasting it directly into the window. Make sure to change the element titled 'USBdrive' for the name of the drive you intend to become the bootable installer.
sudo /Applications/Install macOS Catalina.app/Contents/Resources/createinstallmedia — volume /Volumes/USBdrive — /Applications/Install macOS Catalina.app
Once pasted and corrected, press enter, then enter your password for macOS and press enter again.
Terminal will then warn of the USB drive being wiped as part of the process. Type 'Y' and press enter. Leave the Mac alone as it formats and copies over the installer.
Once Terminal says 'Install media now available,' it is safe to right-click the removable drive on the desktop renamed 'Install macOS Catalina' and select the 'Eject' command. It is now safe to remove the drive from the Mac.
Upgrading another Mac
Before proceeding, ensure there are adequate backups available for the Mac you are about to upgrade before the process starts.
With the target Mac you want to upgrade turned off, connect your external drive. When turning on the Mac, hold down the Option key on the connected keyboard to bring up the Startup Manager.

The Startup Manager is used to boot from a different drive from the default. In this case, select 'Install macOS Catalina.'

The Mac will then bring up a macOS Utilities window. To perform a straight update, select 'Install macOS' and follow the prompts.

The macOS Utilities menu also allows you to erase the Mac's drive, which you can optionally do if you do not wish to save any of the data and want a completely clean slate for the installation.
