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.

  • 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.


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

  • 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.

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.

  • 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.

7. Fill User Profile

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

  • 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.


Once finished, Ubuntu 20.10 says Installation Complete so click Restart Now to enjoy your new computer. Congratulations!
