Struct HybridBootOptions 

pub struct HybridBootOptions {
    pub partition_scheme: PartitionScheme,
    pub mbr_bootstrap: Option<Vec<u8>>,
    pub bootable: bool,
    pub efi_boot_partition: Option<String>,
}

Available on crate features sync and write only.

Hybrid boot options for creating bootable ISO images from USB/disk.

This enables the ISO to be bootable when written directly to a USB drive or other storage media, in addition to being bootable as a CD/DVD.

Fields

partition_scheme: PartitionScheme

The type of partition table to write.

mbr_bootstrap: Option<Vec<u8>>

Optional MBR bootstrap code to inject (must be 446 bytes or less). This is typically the first stage of a bootloader like GRUB or Syslinux.

bootable: bool

Whether to mark the ISO partition as bootable in the MBR.

efi_boot_partition: Option<String>

Path (in the ISO tree, using the configured path separator) of the El Torito UEFI boot image to additionally expose as a GPT EFI System Partition.

Applies to PartitionScheme::Gpt and PartitionScheme::Hybrid. When None, and the El Torito options contain exactly one PlatformId::UEFI section entry, that entry’s boot image is exposed automatically. Formatting fails with a not-found error when the configured path does not resolve to a file in the ISO tree.

Implementations

impl HybridBootOptions

pub fn mbr() -> Self

Create options for MBR-only hybrid boot (BIOS systems).

pub fn gpt() -> Self

Create options for GPT-only boot (UEFI systems).

pub fn hybrid() -> Self

Create options for hybrid MBR+GPT boot (dual BIOS/UEFI systems).

pub fn bootstrap(self, bootstrap: Vec<u8>) -> Self

Set the MBR bootstrap code.

pub fn with_efi_boot_partition(self, path: impl Into<String>) -> Self

Set the path of the El Torito UEFI boot image to expose as a GPT EFI System Partition. See HybridBootOptions::efi_boot_partition.
