    • The desktop installer ISO from copied to the installation media (usually a USB flash drive, but may look like a DVD or ISO list attached to the virtual hypervisor) Machines.

    • Empty installation media (existing processes or data is missing, or the entire computer may be overwritten)

    It is also important to select the correct boot mode before initializing the installer. Ubuntu (and variants like Kubuntu, Lubuntu, Xubuntu, etc.) Use hybrid boot images with two alternate boot loaders:

    1. GRUB (GRand Unified Boot Loader)
    2. Syslinux

    ISO images can be loaded in several possible combinations of mode and separation:

    1. ISO-9660 El-Torito (Optical CD / DVD download mechanism – uses Syslinux)
    2. GPT + EFI-SP (GUID Partition Table, then System Partition EFI – uses GRUB)
    3. MBR + EFI-SP (Master Record work shoes and EFI system partition – use runs GRUB)
    4. GPT + PC (GUID Partition Table and BIOS Boot – Syslinux required)
    5. MBR + PC (Master Boot and BIOS Boot – Works with Syslinux)

    Boot Modes

    PCs have two connection modes: BIOS (Basic Input / Output System) and UEFI (Unified Extensible Firmware Interface). BIOS has been installed on IBM and compatible computers since the 1980s. UEFI has been in widespread use since Microsoft introduced it in Windows 7, in addition to more recent requirements that require it on new computers to comply with the Windows Logo License Agreement. Since 2010, most personal computers have installed the UEFI interface.

    Apple Macintosh / iMac inventions have their own Extensible Firmware Interface (EFI), which is almost, but not necessarily completely, the same UEFI, because, on the contrary, it does not look like BIOS. This does not (currently) install the address block on Apple devices.

    BIOS can be known as an alternative to Legacy Compatibility Support Module (CSM) if it is part of UEFI.

    If the target system is BIOS only, the restYou can skip the rest of this section.

    Select UEFI Learning Mode

    To support UEFI Secure Boot, or install it on another performance system that uses the UEFI form of boot (like Windows 10), you need to train the Boot Manager firmware on your motherboard to use the Ubuntu Installer to start in UEFI mode.

    Unfortunately, there is no consensus among various PC manufacturers as to what to do with the motherboard and how the firmware download managers should tell you the boot mode. see PC boot menu displayed with boot device lists.

    Let’s say our company uses a USB flash drive. The boot menu list can be processed twice (once for UEFI mode, then again for BIOS / CSM / Legacy mode). This tool explicitly states that one may be “UEFI” and the other may not, it may use directives that are difficult to recognize as a one-letter abbreviation (for example, “U” instead of “B”).

    If we all want to guarantee UEFI mode to avoid BIOS / CSM / Legacy mode obtained by micropWith the power-on configuration graph, we really should be able to come up with an alternative to disabling CSM / Find Legacy Mode.

    After that, we can be sure that the installer will boot using UEFI technology.

    There is a quick way to confirm that the installer booted in UEFI mode – it will no longer use GRUB, so see the section below on the first splash screen> GRUB (UEFI mode) for how it should look. …

    Detects Linux Boot Mode With UEFI

This powerful and easy-to-use tool can quickly diagnose and fix your PC, increasing performance, optimizing memory, and improving security in the process. Don't suffer from a sluggish computer any longer - try ASR Pro today!

    After downloading, you can check. The presence of some kind of efivarfs filesystem means the system was booted in UEFI mode:

     add $ | grep efivarsSorting efivarfs in / sys / firmware / efi / efivarfs efivarfs (rw, nosuid, nodev, noexec, relatime) 

    First Splash Screen

    The options displayed should differ depending on the bootloader used.

    GRUB (UEFI mode)

    Select Try Ubuntu Without Installing from the bootloader grub menu:

    Syslinux (BIOS mode)

    Display pauses to select the displayed entry, language:

    If you interrupt thisFrom the step to select the code, Syslinux will display a menu where you can make various additional changes to the startup parameters. At this point, you need to select the “Try Without Installing Ubuntu” menu item.


    If the startup process was not recently interrupted to select a language, this welcome dialog box with startup options may be displayed. Select Try Ubuntu.

    Live Desktop

    Once Live Desktop Planet is up and running, we need to use an absolute terminal shell command line to create a series of commands to prepare the target device before launching the installer itself.

    For media coverage of Ubuntu (Gnome), the Show Applications button above the lower left corner

    Enter “Term” in the exploration text box below until only the terminal symbol is displayed normally.

    Instead of these steps, you can simply press the key combination Ctrl + Alt + T.

    Prepare Encrypted Partitions

    Increasing the terminal time period can be useful when working with this command line.

    It is likely that these manual steps will be saved to preserve the layout and title of the installation that the installer will use.

    You need elevated privileges to enable commands. This change is for the root user (the rr prefix indicates a regular user and therefore # indicates the root user):

    Note that full disk encryption is actually achieved when installing the entire Ubuntu desktop operating system. It encrypts all partitions inincluding external swap space, system partitions, and every bit using data stored in blocksets.

    Step 1. Install encryption packages.Step two: create another user and assign sudo permissions.Step 3. Encrypt your home directory.Step 4: Confirm encryption when registering passphrase.Step 5: Encrypt specific swap space.Step 6: clean up.
