+To build an UEFI capable image,
+
+1. Two partitions are created with GPT partition table. First partition
+   contains the root file system, while the second partition is an EFI
+   System Partition(ESP). ``parted`` is used for creating partitions.
+
+2. As part of installing grub boot loader, the ESP is mounted
+   to /boot/efi directory of the root file system so that grub will
+   install required grubx64.efi and other dependent packages on ESP.
+
+3. Grub configuration files are modified to work with respective
+   distributions.
