Sudo mount -o loop ~/isoĬhange into the directory where we will be doing our work: cd ~/ubuntuĬreate a preseed file that will use LVM to auto-partition the disk using all available space: sudo nano ~/ubuntu/ks.preseed

Mount it and extract its contents to a new folder: sudo mkdir -p ~/iso Here are the steps to create an EFI-bootable ISO: The result is a base Ubuntu Server installation with ubuntu-server and openssh-server only. If you use this ISO on a non-EFI system (for example a Generation 1 Hyper-V VM) then it will wait at the graphical installer startup screen and require input before continuing to the auto installer. If you use this ISO on an existing Linux system then the installer will stop when it detects existing disks and wait for input. This is designed for automatically provisioning new systems with Ubuntu 14.04 using LVM and auto-partitioning. When EFI booting on a system with a blank, uninitialized disk (for example on a new Generation 2 VM in Hyper-V), setup will start automatically, then automatically wipe the disk and install the base ubuntu-server packages and OpenSSH. These instructions will let you create a custom Ubuntu 14.04 Server ISO that can boot EFI and MBR. I was able to piece together the right steps to create an ISO like this. The standard Ubuntu 14.04 圆4 ISO file works this way but there are no instructions available to make a new 14.04 bootable ISO for EFI systems.

You need to make a dual boot catalog ISO so that it will boot EFI and MBR.
