Transfer ISO to target medium (configs/releng)
|
||||
==============================================
|
||||
|
||||
ISO images names consist of: ``archlinux-YYYY.MM.DD-x86_64.iso``.
|
||||
|
||||
Where: ``YYYY`` is the year, ``MM`` the month and ``DD`` the day.
|
||||
|
||||
.. contents::
|
||||
|
||||
Burn to an optical disc
|
||||
=======================
|
||||
|
||||
.. note::
|
||||
All ISO images are BIOS and UEFI bootable via "El Torito" in no-emulation mode.
|
||||
|
||||
Burn the ISO using your favorite disc burning program.
|
||||
|
||||
For example:
|
||||
|
||||
.. code:: sh
|
||||
|
||||
xorriso -as cdrecord -v -sao dev=/dev/sr0 archlinux-YYYY.MM.DD-x86_64.iso
|
||||
|
||||
Write to an USB flash drive / memory card / hard disk drive / solid state drive / etc.
|
||||
======================================================================================
|
||||
|
||||
.. tip::
|
||||
See https://wiki.archlinux.org/title/USB_flash_installation_medium for more detailed instructions.
|
||||
|
||||
Nomeclature:
|
||||
|
||||
``<DEV-TARGET>``
|
||||
Device node of the drive where ISO contents should be copied (example: ``/dev/sdx``).
|
||||
``<DEV-TARGET-N>``
|
||||
Device node of the partition on ``<DEV-TARGET>`` (example: ``/dev/sdx1``).
|
||||
``<FS-LABEL>``
|
||||
Represents the file system label of the ``archlinux-YYYY.MM.DD-x86_64.iso`` (example: ``ARCH_201703``).
|
||||
|
||||
ISOHYBRID (BIOS and UEFI)
|
||||
-------------------------
|
||||
|
||||
.. note::
|
||||
This method is the most easily, quick and dirty, but is the most limited if you want to use your target medium
|
||||
for other purposes. If using this does not work, use the `File system transposition (UEFI only)`_ method instead.
|
||||
|
||||
Directly write the ISO file to the target medium:
|
||||
|
||||
.. code:: sh
|
||||
|
||||
dd bs=4M if=archlinux-YYYY.MM.DD-x86_64.iso of=<DEV-TARGET> conv=fsync oflag=direct status=progress
|
||||
|
||||
File system transposition (UEFI only)
|
||||
--------------------------------
|
||||
|
||||
This method extracts the contents of the ISO onto a prepared UEFI-bootable volume.
|
||||
|
||||
If your drive is already partitioned and formatted, skip to the "Mount the target file system" step.
|
||||
|
||||
.. note::
|
||||
Using MBR with one FAT formatted active partition is the most compatible method.
|
||||
|
||||
1. Partition the drive with *fdisk*.
|
||||
|
||||
.. code:: sh
|
||||
|
||||
fdisk <DEV-TARGET>
|
||||
|
||||
1) Create a new MBR partition table with command ``o``.
|
||||
|
||||
.. warning::
|
||||
This will destroy all data on the drive.
|
||||
|
||||
2) Create a new primary partition with command ``n`` and set its type code to ``0c`` with command ``t``.
|
||||
|
||||
3) Mark the partition as bootable with the ``a`` command.
|
||||
|
||||
4) Write the changes and exit with ``w``.
|
||||
|
||||
2. Format the newly created partition to FAT32
|
||||
|
||||
.. code:: sh
|
||||
|
||||
mkfs.fat -F 32 /dev/disk/by-id/<TARGET-DEVICE>-part1
|
||||
|
||||
3. Mount the target file system
|
||||
|
||||
.. code:: sh
|
||||
|
||||
mount <DEV-TARGET-N> /mnt
|
||||
|
||||
4. Extract the ISO image on the target file system.
|
||||
|
||||
.. code:: sh
|
||||
|
||||
bsdtar -x --exclude=boot/syslinux/ -f archlinux-YYYY.MM.DD-x86_64.iso -C /mnt
|
||||
|
||||
5. Unmount the target file system.
|
||||
|
||||
.. code:: sh
|
||||
|
||||
umount /mnt
|
||||
|
||||
Manual formatting (BIOS only)
|
||||
-----------------------------
|
||||
|
||||
.. note::
|
||||
These steps are the general workflow, you can skip some of them, using another file system if your boot loader
|
||||
supports it, installing to another directory than ``arch/`` or using more than one partition. Just ensure that
|
||||
main boot parameters (``archisolabel=`` and ``archisobasedir=``) are set correctly according to your setup.
|
||||
|
||||
Using here a MBR partition mode as example, but GPT should also work if the machine firmware is not broken. Just
|
||||
ensure that partition is set with attribute ``2: legacy BIOS bootable`` and use ``gptmbr.bin`` instead of
|
||||
``mbr.bin`` for syslinux.
|
||||
|
||||
1) Create one partition entry in MBR and mark it as "active" (bootable).
|
||||
|
||||
.. note::
|
||||
Type ``b`` for FAT32, ``83`` for EXTFS or ``7`` for NTFS.
|
||||
|
||||
.. code:: sh
|
||||
|
||||
fdisk <DEV-TARGET>
|
||||
|
||||
2) Create a FAT32, EXTFS or NTFS file system on such partition and setup a label.
|
||||
|
||||
.. note::
|
||||
COW is not supported on NTFS.
|
||||
|
||||
.. code:: sh
|
||||
|
||||
mkfs.fat -F 32 -n <FS-LABEL> <DEV-TARGET-N>
|
||||
mkfs.ext4 -L <FS-LABEL> <DEV-TARGET-N>
|
||||
mkfs.ntfs -L <FS-LABEL> <DEV-TARGET-N>
|
||||
|
||||
3) Mount the target file system.
|
||||
|
||||
.. code:: sh
|
||||
|
||||
mount <DEV-TARGET-N> /mnt
|
||||
|
||||
4) Extract the ISO image on the target file system.
|
||||
|
||||
.. code:: sh
|
||||
|
||||
bsdtar -x --exclude=boot/grub/ --exclude=EFI/ -f archlinux-YYYY.MM.DD-x86_64.iso -C /mnt
|
||||
|
||||
5) Install the syslinux boot loader on the target file system.
|
||||
|
||||
.. code:: sh
|
||||
|
||||
extlinux -i /mnt/boot/syslinux
|
||||
|
||||
6) Unmount the target file system.
|
||||
|
||||
.. code:: sh
|
||||
|
||||
umount /mnt
|
||||
|
||||
7) Install syslinux MBR boot code on the target drive.
|
||||
|
||||
.. code:: sh
|
||||
|
||||
dd bs=440 count=1 conv=notrunc if=/usr/lib/syslinux/bios/mbr.bin of=<DEV-TARGET>
