Some of the latest laptop and netbooks manufacturers don’t use a CD/DVD drive in their models in order to achieve a thinner compact device. In such cases, you will have to depend on USB to install Ubuntu.
If you are trying to install Ubuntu on an older system, you need to check if the system allow booting from USB. If not, you will have to install Ubuntu the old way, by installing from CD/DVD drive.
Requirements to make Ubuntu bootable
- Download a CD image or .iso image of Ubuntu
- A USB flash drive with a minimum 2GB space. There should not be any files inside the flash drive as the drive needs to be formatted while making it bootable. The .iso file that I downloaded for this tutorial is 753MB.
- Download and Install Universal USB Installer
Steps to make USB bootable Ubuntu
- Connect the USB drive to your computer
- Run Universal-USB-Installer.exe that was downloaded
- Click I agree on license agreement
- Under Step 1, select Try Some Other Live Linux ISO
- Under Step 2, browse to the location where .iso Ubuntu image was downloaded
- Under Step 3, select your Pen Drive or Flash Drive. Also check the option “we will format <drive letter> as FAT32”
- Click Create.
The entire process takes few minutes to format and copy the installer files inside the pen drive.
Once the process is complete, safely eject the drive. Label the drive and keep it safe to prevent accidental usage and losing the drive.
How to boot Ubuntu from USB
- Turn on your computer
- As soon as the computer is turned on, press Delete, F2 or ESC button (depends on manufacturer) to enter BIOS
- Check for an entry which says Boot Configuration or something related to booting (This entry differ depending on the manufacturer of the device).
- Go to the boot options or boot order and select USB as the first boot device (Usually it will be CD/DVD or Hard disk)
- Press F10 to save the changes made to BIOS. (Usually it Is F10. It might be different for a different manufacturer or model)
- Restart computer.
On restarting computer, you will be taken to a purple Ubuntu boot screen. If not, you may not have configured the BIOS correctly or the Ubuntu file inside the pen drive is not bootable.
How to check if the Ubuntu inside pen drive is bootable
Connect the pen drive to your computer. If Auto play window open up automatically, the Ubuntu inside is bootable. Some computers have auto play disabled for better security. Those cases, you can right click on pen drive and click Auto play option. If the window pops up, the Ubuntu inside is bootable.
