Unlocking the Power of Linux with EFI: A Comprehensive Guide（linuxefi）
The power of Linux can be quite astonishing, but many users struggle with unlocking its full potential, particularly when trying to boot and install the operating system on computers, especially those with the UEFI (Unified Extensible Firmware Interface) firmware, or EFI.
Fortunately, the power of Linux can be unlocked with EFI, and this comprehensive guide will explain step-by-step how to do just that.
The first step is to repartition the hard drive and create the necessary partitions. Connect an external hard drive to the computer, then boot up a live distro of a Linux operating system such as Ubuntu or Mint. From there, you’ll need to use the gparted partition editor to create the EFI, root, swap, and home partitions.
After the partitions are created, the next step is to install the operating system. To do this, boot up the live distro and open the installer, then select ‘install alongside existing OS’. Select the EFI partition you created earlier, as well as the other partition you want to install Linux onto. Then, choose your installation type (normal, minimal, etc.), and finish the installation process.
Once the operating system is installed, next up is adding the boot entry to the EFI. To do this, you’ll need to mount the EFI partition and open the efibootmgr command line utility. To view the boot entries, run “efibootmgr -v”.
Once the boot entries are visible, it’s time to add the boot entry for Linux. To do this, type “efibootmgr –create –disk /dev/sdx –part x –label ‘ubuntu’ –loader ‘\EFI\ubuntu\shimx64.efi’ –timeout 10”, substituting the disk and partition you installed Linux onto instead of ‘sdx’ and ‘x’, respectively. This will create the Linux boot entry.
The last step is to adjust the system settings. To do this, reboot your computer and enter the BIOS/UEFI setup. From here, you can set the boot order, select which boot entry to boot from, and modify other necessary settings.
Unlocking the power of Linux with EFI is not overly complicated, and is definitely worth the effort. After following this comprehensive guide, you should now have an EFI-ready Linux installation, and can properly boot the operating system when needed. It’s always a good idea to back up the EFI partition, just in case something goes wrong during the process. Have fun, and happy tinkering!
