The `BOOTX64.EFI` file is a vaild EFI application that can be simply copied to the
`/EFI/BOOT` directory of a FAT32 formatted EFI system partition. This file can be
`/EFI/BOOT` directory of a FAT formatted EFI system partition. This file can be
installed there and coexist with a BIOS installation of Limine (see below) so that
the disk will be bootable by both BIOS and UEFI.

### BIOS CD-ROM ISO creation
In order to create a bootable BIOS ISO with Limine, place the `limine-cd.bin`,
`limine.sys`, and `limine.cfg` files into a directory which will serve as the root
of the created ISO.
### BIOS/UEFI hybrid ISO creation
In order to create a hybrid ISO with Limine, place the `limine-eltorito-efi.bin`,
`limine-cd.bin`, `limine.sys`, and `limine.cfg` files into a directory which will
serve as the root of the created ISO.

*Note: `xorriso` is required.*
`<relative path of limine-cd.bin>` is the relative path of `limine-cd.bin` inside
the root directory.
For example, if it was copied in `<root directory>/boot/limine-cd.bin`, it would be
`boot/limine-cd.bin`.
### UEFI CD-ROM ISO creation

-no-emul-boot <root directory> -o image.iso
limine-install image.iso
```
*Note: `xorriso` is required.*
`<relative path of limine-cd.bin>` is the relative path of
`limine-cd.bin` inside the root directory.
For example, if it was copied in `<root directory>/boot/limine-cd.bin`,
it would be `boot/limine-cd.bin`.
`<relative path of limine-eltorito-efi.bin>` is the relative path of

For example, if it was copied in `<root directory>/boot/limine-eltorito-efi.bin`,
it would be `boot/limine-eltorito-efi.bin`.
### BIOS+UEFI CD-ROM ISO creation
Additionally, it is possible to combine the 2 aformentioned commands into a single one
in order to create a CD ISO which will boot on both BIOS and UEFI:
```
xorriso -as mkisofs -b <relative path of limine-cd.bin> \
-no-emul-boot -boot-load-size 4 -boot-info-table \
-eltorito-alt-boot -e <relative path of limine-eltorito-efi.bin> \
-no-emul-boot <root directory> -o image.iso
```
### BIOS+UEFI hybrid CD-ROM ISO creation
A hybrid ISO that can also be booted when flashed on USB sticks or hard drives
can be made with the following commands:
```
xorriso -as mkisofs -b <relative path of limine-cd.bin> \
-no-emul-boot -boot-load-size 4 -boot-info-table -part_like_isohybrid \

### Example
For example, to create an empty image file of 64MiB in size, 1 echfs partition
on the image spanning the whole device, format it, copy the relevant files over,
and install Limine, one can do:
```bash
dd if=/dev/zero bs=1M count=0 seek=64 of=test.img
parted -s test.img mklabel msdos
parted -s test.img mkpart primary 1 100%
parted -s test.img set 1 boot on # Workaround for buggy BIOSes
