Arch Linux dual secure boot with Windows 11

  • secure boot
  • encrypted root Arch Linux partition
  • Windows 11 with bitlocker on C partition
  • enable TPM2

Download Arch Linux and Windows 11 ISO

Arch Linux ISO: https://archlinux.org/download/ Windows 11 ISO: https://www.microsoft.com/software-download/windows11

Create bootable usb drive

Prepare at least 8 GiB flash drive Download ventoy: https://www.ventoy.net/en/index.html

For those that already have Arch Linux installed, install ventoy-binAUR Before plug in your usb drive, view all available drive fisrt

$ lsblk

Then, plug in your usb drive and once again view the available drive

$ lsblk

A new drive should appear, for example /dev/sda1.

└─nvme0n1p1               259:1    0 465.8G  0 part

Install ventoy on /dev/sda

Disable Windows 11 hardware check

Copy the ISOs to /dev/sda1

Install Windows 11

Boot into UEFI, choose ventoy. Select Windows 11 ISO Allocate 250 GiB for Windows Proceed to installation Reboot

Install Arch Linux

Boot into UEFI, choose ventoy. Select Arch Linux ISO
