  • How to reload OS with Ubuntu 20

    Could someone provide me with the proper steps to reload the Operating System in Ubuntu 20? I have attempted the process several times, but have been unsuccessful. I would greatly appreciate any guidance in this matter. Thank you.

    This following steps will show you how to reload OS with Ubuntu 20.

    Step 1: Connect the ISO through IPMI.

    Step 2: In the BIOS, modify the boot option.

    "CD/DVD" should be the first boot item, and the system disc should be the second boot item.

    Step 3: Continue with the installation.
    • Select the language of choice along with the default options.
    • Set up the network.
    • Leave the proxy field blank.
    • Make use of the default archive mirror.
    • Make use of the custom storage structure.
    • Format every disc.
    Make the partitions.
    • Case 1: If an SSD product is planned, the discs should be configured using RAID. Please perform the following:
    Please select one disc as the boot device and then create two partitions: 4GB and the rest of the available space. Please keep the two partitions in their "unformatted" state.

    Please choose the other disc and divide it into two parts: 4GB and any remaining space. Please keep the three partitions in their "unformatted" state.

    Click "Create software RAID" and make two RAID 1s, one of which has two 4GB partitions and is mounted to "Swap". The alternative one creates two partitions and then mounts them as "/".
    • Case 2: If the server is a bare metal or GPU device, we only need to construct system disc partitions.
    Please only make two partitions: 4GB for swap and the rest of the space should be mounted to "/".

    Step 4: Set up a profile.

    Step 5: Install OpenSSH.

    Following that, the operating system will start the installation process. When it is finished, simply remove the ISO and hit "Enter", and the server will reboot automatically. When it is finished rebooting, you are going to see the login page, at which point you should check if SSH is accessible.
