Installation of Ubuntu

Installing Ubuntu on an external hard disk drive (HDD) connected to my computer that’s already running another operating system which is Windows 8.1.

Step-by-step of installing Ubuntu :

Turn off the computer and put in the DVD. Then, press F10 and enter “BIOS Setup”. Across the top are four menu items. Use the right arrow to higlight the third one, “System Configuration”. A screen offers five options; use the down arrow to select the fifth, “Boot options” and press enter. Under the UEFI boot order, select the “Internal CD/DVD ROM Drive”.

After the computer has booted, it will be presented with the choices shown in the screen shot below. Then, I did chose Install Ubuntu.

Prepare to install UbuntuWhen I boot from the installation disc, it were given the option of booting into a Live desktop or straight to the installer. Then, click past the first step of the installer to get to the step shown in this screen shot. Continue.

Partition MethodsThis step shows available partition methods. I’ll need to be doing a manual partitioning of the target HDD. That is the only way I can be sure that I’ll not be erasing the contents of the internal HDD. So, I clicked on the “Something else” option. Continue.

Advanced Partitioning Tool.It brought me to the Advanced Partitioning Tool’s window. This step showed all the HDDs detected by the installer and their partitions.

Create partition Notice that the size of the external HDD is 320 GB. However, I do not intend to use all that disk space for Ubuntu 13.10, just about half of it. With regards to creating the partitions, the goal is to create the same set of partitions on a default installation of Ubuntu 13.10. That means creating just two partitions; the main partition mounted at / (root) and a Swap partition.

Partition EditorThis is the partition editor’s window. With no existing partitions on the HDD, the installer will set up the options to create a primary partition. The only thing I changed was the size and mount point. The default file system is ext4, which I didn’t change.

Create Root PartitionFor the root partition, I chose to allocate 150 GB to it. Then, click “ok”.

Back to the main partitioning window, the partition just created should be listed below sdb. Select the free space and click the + button

Back here again. By default, the installation will want to create the next partition as a logical partition.

Create Swap Partition. So I allocated the Swap partition just 2000 MB (2 GB).
