Bypassing Secure Boot for Installing Arch Linux Alongside Windows 11

Bypassing Secure Boot to Install Arch Linux Alongside Windows 11

In this article, we will discuss the process of installing Arch Linux alongside Windows 11, with a focus on bypassing Secure Boot. Secure Boot is a security feature in modern computers that prevents unauthorized firmware, operating systems, or bootloaders from running. However, it can also prevent us from installing our preferred Linux distribution.

Prerequisites

Before we begin, make sure you have the following:

• A computer with Windows 11 installed.
• At least 30 GB of free space for Arch Linux.
• A USB drive with at least 8 GB of storage for the Arch Linux installation media.

Creating the Arch Linux Installation Media

First, download the latest version of Arch Linux from the official website and use a tool like Rufus or Etcher to create a bootable USB drive.

Disabling Secure Boot

To disable Secure Boot, follow these steps:

1. Restart your computer and enter the BIOS settings.
2. Navigate to the Security tab and select Secure Boot.
3. Set Secure Boot to Disabled and save the changes.

Installing Arch Linux

Now that Secure Boot is disabled, we can proceed with the installation:

1. Boot your computer from the Arch Linux USB drive.
2. Connect to the internet using a wired or wireless connection.
3. Partition the hard drive using a tool like fdisk or parted.

fdisk /dev/sda
n
p
1

+30G
a
1
w

4. Format the partition using a filesystem like ext4:

mkfs.ext4 /dev/sda1

5. Mount the partition:

mount /dev/sda1 /mnt

6. Install the base system:

pacstrap /mnt base base-devel linux linux-firmware

7. Generate the fstab file:

genfstab -U /mnt > /mnt/etc/fstab

8. Chroot into the new system:

arch-chroot /mnt

9. Configure the system:

nano /etc/locale.gen
locale-gen
echo LANG=en\_US.UTF-8 > /etc/locale.conf
ln -sf /usr/share/zoneinfo/America/New\_York /etc/localtime
hwclock --systohc
echo root:password | chpasswd
passwd

10. Install a bootloader:

pacman -S grub efibootmgr
grub-install --target=x86\_64-efi --efi-directory=/boot --bootloader-id=ArchLinux
grub-mkconfig -o /boot/grub/grub.cfg

11. Exit and reboot:

exit
umount -R /mnt
reboot

Re-enabling Secure Boot

Once Arch Linux is installed and booting correctly, you can re-enable Secure Boot if desired:

1. Restart your computer and enter the BIOS settings.
2. Navigate to the Security tab and select Secure Boot.
3. Set Secure Boot to Enabled and save the changes.
