A slightly modified version of the officical archiso tool, including xorg and configs to create a dual-boot USB with Windows installation media

Building

Same as always (https://wiki.archlinux.org/index.php/Archiso), pacman.conf needs some tweaking to point to a repository that has all the required AUR packages built (see packages.both).

Partitions

Device: /dev/sdx

• archiso (vfat) - /mnt/arch
• windows (vfat/ntfs) - /mnt/win
• cowspace (ext4, label ARCHISO_COW)

Installing

1. Write contents of Arch ISO to /mnt/arch

2. woeusb -p win.iso /dev/sdx[n] (= /mnt/win)

3. mv /mnt/win/efi/boot/{bootx64,windows}.efi

4. Install grub:

   grub-install --target=x86_64-efi --efi-directory=/mnt/arch --boot-directory=/mnt/arch --removable --recheck
   grub-install --target=i386-pc --boot-directory=/mnt/arch --recheck /dev/sdx
   

5. Copy grub config cp archiso/grub.cfg /mnt/arch/grub/

6. Change values in grub config:

   • archiso_uuid and windows_uuid to the filesystem UUID of /mnt/arch and /mnt/win (i.e. from lsblk -f)
   • archiso_basedir to the one supplied to ./build.sh -D (default "arch")
   • archiso_label to the label of /mnt/arch (default ARCH_%Y%m)
