Portable ZFSBootMenu
|
|
====================
|
|
|
|
UEFI makes it easy to deploy ZFSBootMenu without a local installation. Most
|
|
UEFI systems will search for and run an EFI executable at the path
|
|
``/EFI/BOOT/BOOTX64.EFI`` on a FAT-formatted `EFI System Partition`_
|
|
located on any disk that the firmware is told to boot. This executable can be a
|
|
standard ZFSBootMenu release image or a custom, locally generated image. Almost
|
|
any modern system can be made to launch a ZFSBootMenu instance just by
|
|
inserting and booting from a minimally configured USB drive.

Procedure
|
|
---------
|
|
|
|
1. On a USB drive, create a GPT header.
|
|
|
|
2. Create an `EFI system partition`_ on the drive. The partition should be at
|
|
least 100 MB.
|
|
|
|
* With `gdisk <https://man.voidlinux.org/gdisk.8>`_, this is accomplished by
|
|
setting the parition type to ``EF00``.
|
|
|
|
* With `parted <https://man.voidlinux.org/parted.8>`_, this is accomplished
|
|
by setting the ``boot`` flag on the partition.
|
|
|
|
3. Format the partition as FAT.
|
|
|
|
4. Fetch a copy of the ZFSBootMenu release image:
|
|
|
|
.. code-block:: sh
|
|
|
|
curl -LJO https://get.zfsbootmenu.org/efi
|
|
|
|
5. Save the resulting download as ``EFI/BOOT/BOOTX64.EFI`` within the EFI
|
|
system partiton.
|
|
|
|
6. Tell your system to boot from the USB drive.
