Installing Ubuntu in virtualbox
Download virtualbox and extensions
Choose Linux, Ubuntu 64 and a name like Ubuntu.
Choose RAM size. I used 2048 MB because it is recommended for Ubuntu 16.04
Choose Hard Disk size. I chose 15 GB and “create virtual hard disk file.”
Choose Hard disk file type. I left it at VDI.
Choose Storage on physical hard disk. I used fixed size because it faster.
Choose Location and size. Ubuntu
Choose Virtualbox – preferences – extensions and install the Virtualbox extensions you downloaded. The extensions enables USB 3.
I upgraded the settings on the Ubuntu virtual machine:
Ubuntu – settings:
ports – USB – USB 3
Video – Memory – 128 MB
System – Processor 2 CPUs (Ubuntu 16.04 minimum requirements)
Choose the ubuntu linux image when you boot it the first time or add is as a cd rom.
You can now start the virtual machine.
Choose install Ubuntu
I used the default settings.
When Ubuntu is installed you can install the linux Guest additions.
Use Virtualbox – Devices – Install Guest Additions. The Guest additions enables adjusting the screen size of the virtual box and other things.
Let the program run.
You can set up a Shared folder in virtualbox that will be mounted in linux
Devices – Shared folder – Shared folder settings

Use add partition, add a label and format the drive as EXT2, NTFS, EXT4 or others.
Format the hard drive using mke2fs with inode 128
