Ubuntu Dual Boot Steps

  • End goal: Ubuntu 20.04 for ROS Noetic Ninjemys

Requirements:

  • A computer with Windows
  • Internet connection
  • A large enough (8gb+) USB stick
  • Rufus or similar software

Steps:

1. Format your USB

  • Go to Library, select your USB, choose format
  • Choose FAT32 for File System then format

2. Allocate space for Linux

We make room for Linux

  1. In Windows, search Create and format hard disk partitions
  2. Choose a disk (m.2 > ssd > mechanical) and choose a volume
  3. Right click on that volume, Shrink Volume, and enter the amount of space to shrink
    • Allocate 75gb - 100gb

3. Prep to download Ubuntu

Make your flash drive a boot device.

  1. In Windows, get the .iso for the correct Ubuntu version
  2. Use Rufus and burn the iso image to the stick
    • Make your file system FAT32

Boot from the USB drive

  1. With the prepped USB drive plugged into the computer, enter BIOS

  2. In BIOS:

    • Enable Boot from USB
    • In Boot Order, move the prepped USB drive all the way to the top. This will allow the computer to boot from the USB instead of whatever was there before (likely Windows)
    • Save changes then exit

  3. Restart the computer to boot from the USB drive

    • Here you should be able to see various Ubuntu options, such as Try Ubuntu without downloading, Install Ubuntu, etc.

  4. Choose the Install Ubuntu option

  • In BIOS, enable Boot from USB and set it to boot from your USB.
  • Restart to enter Ubuntu.
  • Once it loads, choose Install Ubuntu.
  • Continue following instructions until "Installation Type". Once you're there, choose "Something Else".

4. Download Ubuntu

  1. From the same screen above, choose Install Ubuntu
  2. Follow the straight-forward instructions until we get to Installation type

Custom Partitioning

  1. In Installation type, choose Something Else

  2. Here you will see various spaces available in the drive. Select the space we allocated in Step 2 (hint: it says free space)

  3. In the free space:

    a. Create the / partition:

    • Size: about 20gb
    • Primary type
    • Beginning of this space
    • Use as Ext4 journaling file system
    • Mount point: /

    b. Create the Swap partition:

    • Size: 8gb-16gb
    • Primary type
    • Location for the new partition: Beginning of this space
    • Use as swap area

    c. Create the Home partition:

    • Size: As much as possible (the rest of the space)
    • Primary type
    • Location for the new partition: Beginning of this space
    • Use as Ext4 journaling file system
    • Mount point: /home
  • Complete installation by following the rest of the instructions.
