This article explains how to create an UEFI boot USB with parted and gummiboot.
In this example we will use /dev/sdX. This will be different depending on your system.
Create GPT boot partition
Install parted
apk add parted
Create a single UEFI boot partitions.
parted --script /dev/sdX mklabel gpt parted --script --align=optimal /dev/sdX mkpart ESP fat32 1MiB 100% parted --script /dev/sdX set 1 boot on
Create fat32 filesystem
Create a fat32 system with the name `Alpine`.
mkfs.vfat -n ALPINE /dev/sdX1
Copy content of ISO image to filesystem
It is possible to mount the iso image and copy files with cp or rsync and it is also possible to use 7z to extract content from the iso. In this example I will use the uniso utility from alpine-conf package.
mount -t vfat /dev/sdX1 /mnt cd /mnt uniso < /path/to/alpine-3.8.2-x86_64.iso
Unmount the partition
Finally umount the disk
cd ~ && umount /mnt
