Ubuntu 18.04 Installation on Fujitsu AH557

Ubuntu installation on hybrid system


To get a hands-on experience on Ubuntu installation on a UEFI hybrid system.


  • 120 GB SSD disk: /dev/sda
  • 1 TB HDD disk: /dev/sdb
  • 8 GB USB key: /dev/sdc

Stage 0: precautions

  • Ensure that your machine has enough power.
  • Disable Secure Boot in M$ Windows
  • Disable Quick Boot in boot menu

Stage 1: Make your live USB key

I tried Xubuntu’s built-in disk writing tool to create a live USB key from the official ISO file. Like my Xubuntu 18.04 installation on Fujitsu LH532 , the installer crashed during the installation. After submitting the generated report to Launchpad, I found out that the cause for this crash: the integrity test for my live USB key had failed.

Thanks to UNetBootin, I created a live which passed that test.

Moral of the story: verify a live USB drive before installing OS.

Stage 2: Try a live session before installation

I’m sorry for the blurred photos showing the installer. I tried using G’MIC’s octave sharpening in GIMP, after shrinking them to 800 pixels. However, the results didn’t look good. I found keeping media files under 500 kB difficult for an article with a lot of photos.

SSD partition for Ubuntu install

Partitioned a Fujitsu 120GB SSD drive

Partition Type Mount point Approximate Size
free space 1 MB
/dev/sda1 efi 500 MB
/dev/sda2 ext4 / 30 GB
free space rest of the disk

Device for boot loader installation: /dev/sda

HDD partition for Ubuntu install

HDD partition table

Partitioned a Fujitsu 1TB HDD drive

Partition Type Mount point Approximate Size
free space 1 MB
/dev/sdb1 ext4 /home 20 GB
free space rest of the disk
/dev/sdb4 ext4 /tmp 4 GB
/dev/sdb3 ext4 /var 4 GB
/dev/sdb2 swap 16 GB

The basic principle of this partitioning scheme is to place files neccessary for system startup into the SSD, and to keep frequently written files (e.g. system logs, temporary files, etc) and the home folder in the HDD. Regarding the swap, it’s twice the size of the RAM and I placed it at the end of the HDD. (In fact, the position of the swap doesn’t matter according to an Ask Ubuntu question.)

The 1 MB free space at the beginning of each disk was automatically created by the installer.

Since love is a commandment from the church I went last year, I type out the figures in the above photo so that the visually impaired can read them from a text browser (lynx, w3c, etc).

A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another.

Ubiquity installer

Ubuntu 18.04 installation process


Despite the error message inside the black-and-white terminal from the installer, it didn’t pop up in a dialog box.

  1. Reboot the machine .
  2. Configure the boot menu (usually by pressing <F2> or <F12>)
  3. Choose ubuntu as the first option.
  4. Save and exit, then wait for reboot.

This allows the UEFI to load the installed Ubuntu OS without finding other bootable media.

As shown in the previous pictures, Ubuntu’s GRUB bootloader was installed in /dev/sda (i.e. the SSD). As a result, we see ubuntu instead of SSD.

Stage 3: Ubuntu’s warm welcome

After login, I was greeted with a series of messages after the installation.

I format the output using tables so that it’s easier to read.
