Создание UEFI LiveCD образа с iPXE¶

Скачаем вариант ipxe в виде приложения EFI¶

wget http://boot.ipxe.org/ipxe.efi

Cоздаем FAT файловую систему¶

Потребуется sys-fs/mtools

dd if=/dev/zero of=fat.img bs=1k count=1440
mformat -i fat.img -f 1440 ::
mmd -i fat.img ::/EFI
mmd -i fat.img ::/EFI/BOOT
mcopy -i fat.img ipxe.efi ::/EFI/BOOT/BOOTX64.EFI
