UEFI - Install Guide

Introduction

At this stage of the game, installing a Linux distro on a UEFI can be the trickiest part of the installation.

UEFI is the commonly agreed on name for both the EFI & UEFI 
standards which merged. It does not include the old EFI v1, 
or Apple's own non-standard version of EFI.

So the following guide can be a huge time & frustration saver for some users.

Target computer:

The following guide will install Manjaro as the sole installation on a machine with UEFI enabled, Secure boot disabled using GUID Partition Table (GPT) disk(s).

The Simple steps:

1. Download your preferred Manjaro version (XFCE, Openbox, Cinnamon, KDE, ...), must be 64-bits.

2. Burn the .iso to USB or DVD. For Windows users using USB media, Rufus [1] is highly recommended.

2.1. Rufus (Windows) users should use the following settings:

* Click on the DVD icon and load your .iso
* Device: "choose your USB" (Attention: choose correctly,
  the device selected here will be formatted!!!)
* Partition scheme: GPT partition scheme for UEFI computer
* File system: FAT32
* Cluster size: "Don't modify"
* Volume label: "Don't modify"
* Click Start, and you are done (takes 2~5 min to complete).

3. Check your BIOS, UEFI must be ON and Secure boot OFF.

4. Boot with your USB or DVD & use the rEFInd - Main Menu... to choose which GPU drivers you want to have installed, the open-source or proprietary:

* Boot Manjaro Linux ... (default) - 
  This chooses the open-source - free GPU drivers.
* Boot Manjaro Linux ... (nonfree) - 
  This option chooses the proprietary GPU drivers
  from Nvidia or ATI.

5. Open terminal & enter:

$ sudo update-setup
$ sudo setup

6. Now, we are in the CLI Installer (the graphical installer doesn't support UEFI yet).

Choose 2. Use testing installer (EFI support).

7. Choose 1. Set date and time - an easy intuitive configuration.

8. Now, Choose 2. Disk(s) preparation.

Go to 2. Partition Hard Drives or follow the instruction in the next point 8.1 to automatically partition the entire disk.

8.1 If you want to use the entire disk, and don't want to manually configure your partitions, you can choose 1. Auto-Prepare.

Attention: I don't know for sure if using the 
Auto-Prepare option of the installation will be 
successful as I always prefer to manually configure 
my partitions. Give it a try, if you have problems
then please post here: [2]

So, if 8.1 (Auto-Prepare) is chosen, you skip the process below and go to 9...

* When you click 2. Partition Hard Drives, 
  you get a dialog saying "Do you want to use GUID
  Partition Table (GPT)", choose Yes.
* Partition your disk(s) as you want (Instructions on
  manually partitioning are beyond the scope of this
  guide.)
* Important Step: Create a 50~250MB EFI Partition,
  mine is 100MB (code: ef00)
* When you are done, go to 4. Set Filesystem
  Mountpoints. (Again, instructions on manually
  partitioning are beyond the scope of this guide.
* Important Step: Format the EFI Partition you
  created as VFAT and mount on /boot/efi

9. Choose 3. Install system and wait...

10. Now, go to 4. Configure System and configure it the way you like (username, password, mirrorlist, system-name, ...).

11. When you are done, go to 5. Install bootloader. Choose EFI_x86_64 > GRUB (2) UEFI x86_64, or something like that, I don't remember precisely, but it's very, very intuitive, just DON'T select BIOS GRUB.

11.1 It will ask to format the EFI Partition you created earlier as FAT32, just mark Yes.

12. If it gives a error in the final stages saying "efivars kernel module was not properly loaded", don't worry, the system will work fine!

13. If the installer asks you about copying grub/efi files to another folder in order to maintain compatibility in some systems, choose Yes.

14. Click 6. Quit

15. Shutdown, remove the DVD or USB, and boot. Your system should appear now!

DONE, SYSTEM INSTALLED!
