How to Create a USB flash drive for Ubuntu Installation

Many of my friends know that Ubuntu is a very good Linux release. It is also very easy to download Ubuntu from the official website. But after downloading ISO, how can we install it? Of course, in our early years, we installed the software by recording the DVD. Now, as the optical drive is gradually eliminated by the market, Ubuntu keeps pace with the times like Windows, you can also install the USB flash drive on Ubuntu.

Many of my friends know that Ubuntu is a very good Linux release. It is also very easy to download Ubuntu from the official website. But after downloading ISO, how can we install it? Of course, in our early years, we installed the software by recording the DVD. Now, as the optical drive is gradually eliminated by the market, Ubuntu keeps pace with the times like Windows, you can also install the USB flash drive on Ubuntu.

The following describes how to install a USB flash drive in Ubuntu on Windows, Mac, or even Linux.

Ubuntu version Selection

First of all, we need to know that Ubuntu has the LTS version and the "cutting-edge technology version", both of which can be used as daily desktop terminals, but we usually think that the LTS version is more stable, in addition, you can obtain technical support for five years from the date of release. The so-called "cutting-edge technology edition" released between LTS versions only has a nine-month support period. After expiration, users must upgrade to a new version.

Then there is a 32-bit and 64-bit version selection problem. I personally suggest you install the most popular 64-bit version. Of course, if your computer is too old or cannot be supported, install 32-bit. In the past, there was a popular saying that when the memory is smaller than 3 GB, do not select the 64-bit version for installation. In fact, this can be ignored, and 64-bit can make full use of CPU support, even if your memory is less than 3 GB.

Regardless of the version you choose, you can download the ISO installation image from the official website:

Installing a USB flash drive on Ubuntu on Mac is tricky for many common users, because we need to use Mac terminal commands. Of course, the advantage is that you do not need to download the tools that are not commonly used to occupy space.

Open the terminal and run the following command:

First browse to the download folder:

1. Cd ~ /Downloads

Run the following command:

1. Hdiutil convert-format UDRW-o ubuntu. iso ubuntu-xxxxxx.iso

The last part is the file name of the downloaded Ubuntu image. Please replace it as needed before execution. This command can be used to convert an ISO image into a Mac image.

Run the following command to delete the. dmg extension added to the image file for Mac:

1. Mv ubuntu. iso. dmg ubuntu. iso

Next, list the current drive:

1. Diskutil list

Then insert the USB flash disk and run the preceding command again:

1. Diskutil list

Find the drive mount point that is not available before, and then execute:

1. Diskutil unmountDisk/dev/diskN

N is the mount point number of the USB flash disk found in the previous command.

Run the following command to write the Ubuntu image file to the USB flash drive:

1. Sudo dd if =./ubuntu. iso of =/dev/rdiskN bs = 1 m

After the writing is complete, execute the following command to bring up the USB flash drive and make it complete:

1. Diskutil eject/dev/diskN

In Linux, the installation of a USB flash drive for Ubuntu is similar to that for Mac, which is completed by using terminal commands:

First browse to the download folder:

1. Cd ~ /Downloads

1. Sudo dd if =./ubuntu-iso-name.iso of =/dev/sdX

X indicates the mount point of the USB flash drive. Of course, ubuntu-iso-name indicates the name of the downloaded Ubuntu image. You need to modify it yourself.
