This article is to explain how to install the ubuntu system on the U disk (that is, take the U disk as the hard disk of the computer), you can plug the U disk into any computer and run the ubuntu system on the physical computer, and all running configurations can be saved, which is equivalent to a computer you carry with you.

In order to ensure the fluency of installation and operation, please use the USB3.0 flash drive and interface. The capacity of the USB disk should be above 16GB, because the installation will take up close to 3G space.

Note: do not put useful information on the U disk, because the U disk will be formatted during installation and the data will be lost. Please back up the data in the U disk before installation!

Environment and preparation:

This article uses the VMware virtual machine as the boot media for the installation image, and the VMware version is 12.5pro.

You need to download the iso image of ubuntu in advance. Ubuntu lts16.04 is used in this article.

Installation steps:

After preparing the environment, we need to create a new virtual machine in VMware. Be careful to choose the installation source and install the operating system later. Other settings can be set by default or recommended.

Click Virtual Machine Settings after the new virtual machine is created, and fill in the path of the downloaded image in cd as shown in the figure. At the same time, check all the options in the usb controller, and then select USB3.0 for compatibility

Click OK to save the configuration and insert the pre-prepared flash drive. Then click to start the virtual machine. A prompt for an optional mobile device will pop up. If not, please look at the next step first.

If there is no prompt for a mobile device, the usb service for VMware is generally not started. Press and hold the win+r input command service.msc to open the service manager, find VMware USB Arbitrary and then right-click to start, and right-click to select properties to change the startup mode to start.

Close VMware after starting the service, then turn it back on, repeat the previous step, and you should see the prompt.

If you have not found your own USB disk, after starting the virtual machine, link the USB disk to the virtual machine as shown below.

After the above operations, the USB disk can be connected to the virtual machine, and then we select the language to install, click try ubuntu, and then enter a temporary system.

Click install ubuntu in the upper left corner of the desktop and you will enter the installer.

After selecting the language, click continue, and then a prompt window will appear saying that you have multiple devices connected to your computer. Note the key NO here.

Click continue after clicking NO, then select the last something else and continue with continue.

Select dev/sdb and click new partition table to create a new partition table, and then you will be prompted and confirmed.

Then a primary partition of the U disk is divided into etx4, the capacity is set to 15000MB, and a swap partition in the format swap uses the remaining space of the U disk.

Double-click dev/sdb/ntfs and then use as etx4, check format format, and then set mount point to /

Then the bottom device for boot loader must be selected as a flash drive.

The final choice should look like this.

After you finish all this, you will continue all the way. Just wait.

After the installation is completed, you will be prompted to restart. At this time, just unplug the USB drive. Then you can use the ubuntu system on any computer.
