This post will show you how to get up and running with Ubuntu 20.04 on VirtualBox.
You will need to have VirtualBox installed on your workstation. VirtualBox can be downloaded from here.
First you will need to download the Ubuntu 20.04 ISO image from here.
I am working on a 64bit machine so I am going to click on the 64-bit PC (AMD64) desktop image link. When you click on this link the ISO image should start to download.
Once the image is downloaded start up VirtualBox and click on new.
Give your new VM a name and select the appropriate details.
Select an appropriate amount of RAM. The minimum requirement is 1024MiB. Click Next.
Select create a virtual hard disk and click next.
Select VDI and click next.
Select dynamically allocated and click next.
Select a folder location and an appropriate size for your VM disk and click create.
Your VM shell should now be ready. Next you will need to boot into the Ubuntu 20.04 ISO you downloaded earlier.
To do this, in your VirtualBox interface you should see your new VM listed, click on the VM.
Then click on settings.
Now you will need to set the VM to boot from the Ubuntu 20.04 ISO.
Click on storage then controller: IDE and then click on the disk symbol that says empty.
Then under optical drive click the small disk icon and then choose virtual optical disk file and browse to the ISO file you downloaded earlier.
Double click on your ISO file and it should then be connected via the optical drive of your VM. Click ok.
You should now be able to boot into the Ubuntu 20.04 ISO and install Ubuntu on your VirtualBox VM.
Now in the VirtualBox interface select your VM and click on the start button.
Your VM should boot into the Ubuntu Install screen.
Click on install Ubuntu.
Select the appropriate keyboard settings and lick continue.
Again select the appropriate settings and click continue.
Choose the appropriate settings for you. I am selecting Erase disk and install Ubuntu.
When you have are happy with your selections click install now.
Assess the detail on the next screen and click continue if you are happy to proceed.
Next select the region you are in and click continue.
Next enter your required user details and click continue.
Ubuntu 20.04 should now start to install on your VirtualBox VM.
Once complete you will see the following screen.
Click Restart now. When the VM reboots you should be able to log in with the username and password you set earlier.
That's it. Leave a comment below to let me know if this worked for you or not.
