Functions ¶

func AssembleMCTISO ¶

func AssembleMCTISO(_ context.Context, esdPath string, cfg AssembleConfig) error

AssembleMCTISO converts a self-contained MCT ESD into a bootable Windows ISO.

MCT ESD image layout (differs from UUP dump):

image 1: boot files          → extract to staging dir
image 2: WinPE               → export to boot.wim (image 1)
image 3: Windows Setup       → export to boot.wim (image 2, marked bootable)
image 4+: editions (Pro etc) → export to install.wim

No --ref / resource references needed — MCT ESDs are self-contained.

func FetchWindowsISO ¶

func FetchWindowsISO(ctx context.Context, cfg FetchConfig) (string, error)

FetchWindowsISO downloads a self-contained Windows 11 ARM64 ESD from Microsoft's CDN via the MCT catalog and assembles it into a bootable ISO.

MCT ESDs have a different image layout than UUP dump ESDs:

image 1: boot files          → extract to staging dir
image 2: WinPE               → export to boot.wim (image 1)
image 3: Windows Setup       → export to boot.wim (image 2, marked bootable)
image 4+: editions (Pro etc) → export to install.wim
