Install Ubuntu Server 24.04.1 Live Server
on Dell Precision Tower 5810

Notes...

• The internal DVD drive is broken and doesn't work, though I'm pretty sure I installed Linux Mint from an ISO using this drive a few years ago.
• I substituted a USB plug-in DVD (Blu-ray) external drive containing the Ubuntu Server ISO.
• I also attempted to boot from a thumb drive containing the Ubuntu Server ISO; this did not work.
• It appears that the 1Tb SSD cannot be reformatted so is of no use as the boot disk; maybe as a filesystem after the system comes up.

Steps taken...

1. Redo boot sequence to remove all but:
   1. USB booting plus...
   2. the 2Tb hard drive.
2. Reboot and the ISO on the external DVD (Blu-ray) drive will boot.
3. Install Ubuntu Server.
4. When offered to update the installer, accept to do that.
5. Fill in the installation options including use of the 2Tb hard drive.
6. When finished, remove the install media and the external DVD (Blu-ray) drive itself.
7. Reboot using power switch.
8. During reboot, hold down F2 or F12.
9. Set the boot sequence to:
   1. ST2000DM001-1ER164 (2Tb hard drive)
   2. USB Storage Device
10. If the 1Tb SSD is left in the sequence, Linux Mint will boot since that's where I installed it a couple of years ago.
11. The result is always, "No Boot Device Found. Press any key to reboot the machine"

Things to try...

• Review filesystem device formatting during installation to ensure that the 1Tb SSD is not part of the mix.
• Boot to the live installer, then open a terminal to zap the partitions on the 1Tb SSD with a command like wipefs -a /dev/sda.
• It might be good to find the setting and enable UEFI (and even disable Legacy/BIOS boot).
