4 min readDec 30, 2020

This tutorial explains Ubuntu 20.10 Groovy Gorilla installation. You will prepare at least two disk partitions, finishing it all in about twenty minutes, and enjoy! Let’s start right now.

About This Tutorial

This tutorial is practicable for normal installation as well as dual-boot, UEFI, and even external driveways.

Normal: most computer users will need this.
Dualboot: users who want both Ubuntu and Windows on one computer will need this. This needs separate partitions prepared beforehand.
UEFI: users with >=2011 computers will need this. This needs one additional partition called EFI.
External: for users who want to install, not only make bootable, Ubuntu into a flash drive or external hard disk drive. The only difference is where you put the bootloader on.

Preparations

Ask experienced knowledgeable computer users near you for guidance in following this if you have no prior experience in partitioning and doing a backup.

Partitioning Example

First preparation, Download Ubuntu 20.10 and create a bootable flash disk drive using tools like Unetbootin or Rufus, GNOME Disk Utility, or GLIM.

Second preparation, with GParted on LiveCD, create three hard disk partitions:

first one tiniest, a FAT32 by 100MegaByte with label FOR EFI;
the second one a little bit larger, a FAT32 by 1GB with label FOR SWAP; and
the third one the largest, a FAT32 by >=20GB with label FOR ROOT.

For Dualboot mode, make sure you properly backed up important data from Windows and its data partitions to an external storage drive. For BIOS Legacy users, you do not need and simply ignore the making of the EFI partition above. For UEFI users, you do need to make those three partitions. For disk partition size, I recommend a 100GigaByte ROOT for serious and permanent use. For external installation, you can install Ubuntu into a USB Flash Drive or similar device by choosing the correct bootloader location as explained in the partitioning section below.

Booting & Entering Setup

Make sure your BIOS ready, now boot up your computer to USB > then, select Try It instead of Install It on Ubuntu selection screen > you see a pink-orange desktop with a gorilla picture, that is “preview” or LiveCD session, then double click Install Ubuntu 20.10.

1. Select Language

On the first page, select English and continue.

2. Select Keyboard

On the second page, select English (US) and continue. You can change it later to Arabic, Japanese, Chinese, etc. anyway.

3. Select Networking

On the third page, select ‘I don’t want to connect’ and continue.

4. Select Normal

On the fourth page, select Normal Installation instead of Minimal and continue.

5. Select Manual Partitioning

On the fifth page, select Something Else also known as Manual instead of others and continue. You might be asked to do unmounting then do it.

6. Create Disk Partitions & Bootloader

Here you will utilize 3 partitions you have created beforehand.

1. Create EFI partition(*): click the smallest sized partition > Change > switch Use as: to EFI System Partition > OK.
2. Create SWAP partition: click the middle one > Change > switch Use as: to swap > checkmark Format the partition > OK.
3. Create ROOT partition: click the largest one > Change > switch Use as: to EXT4 Journaling Filesystem(**) > check mark Format > select mount point / > OK.
4. Select bootloader install(***): choose the same disk address where you made the ROOT partition above, for example, choose bootloader /dev/sda if your ROOT is /dev/sda1.
5. Click Install Now.

*) BIOS Legacy users do not create this.

**) Choose EXT4 for hard disk, but instead choose EXT2 for installation into USB flash disk.

***) For external install, do not choose the internal hard disk address but choose your external drive address where your ROOT partition is made.

7. Fill User Profile

Here you determine your own timezone then username & password pair.

1. Timezone: click a point on the world map to choose yours. For example, mine is Asia/Jakarta, Indonesia. Go next.
2. Username: determine username > determine computer’s name > determine password > determine either Login Automatically to mimic most Windows computers (for convenience) or log in with Password as usually, Ubuntu users do (for security) > go next.

8. Wait

Now you will only need to wait up to fifteen minutes while enjoying a beautiful slideshow. You can have a cup of coffee or chit chat with friends here. The secret is, here thanks to your choice to Try It (aka LiveCD) earlier, you can even write documents or play audio as you can run all the programs on your screen.
