A method for rolling back an update to an automatic teller machine , comprising: creating, by a host operating system , a virtual hard drive comprising a file system corresponding to a client operating system of the automatic teller machine , the virtual hard drive configured to automatically capture a back-up system image of the client operating system at predetermined intervals; storing, by the host operating system , the back-up system image of the client operating system on the virtual hard drive to create a bootable image of the automatic teller machine , the bootable image comprising the backup system image of the client operating system and a boot loader that defines at least one transformation to be performed on the bootable image to allow the automatic teller machine to boot directly from the virtual hard drive via the back-up system image; deploying, from the host operating system , a system update intended for the client operating system ; determining that the system update failed to install properly on the client operating system and that the automatic teller machine has shut down; emulating, by the host operating system , the virtual hard drive on the automatic teller machine without loading the client operating system ; executing the boot loader to thereby perform the at least one transformation on the bootable image; booting the automatic teller machine using the transformed bootable image; installing, from the virtual hard drive , a rolled-back operating system on to the automatic teller machine , the rolled-back operating system comprising the back-up system image of the client operating system ; receiving a patch that has altered the system update to create a patched system update intended for the client operating system ; and deploying, from the host operating system , the patched system update to the rolled-back operating system on the automatic teller machine . creating, by a host operating system , a virtual hard drive comprising a file system corresponding to a client operating system of the automatic teller machine , the virtual hard drive configured to automatically capture a back-up system image of the client operating system at predetermined intervals; storing, by the host operating system , the back-up system image of the client operating system on the virtual hard drive to create a bootable image of the automatic teller machine , the bootable image comprising the backup system image of the client operating system and a boot loader that defines at least one transformation to be performed on the bootable image to allow the automatic teller machine to boot directly from the virtual hard drive via the back-up system image; deploying, from the host operating system , a system update intended for the client operating system ; determining that the system update failed to install properly on the client operating system and that the automatic teller machine has shut down; emulating, by the host operating system , the virtual hard drive on the automatic teller machine without loading the client operating system ; executing the boot loader to thereby perform the at least one transformation on the bootable image; booting the automatic teller machine using the transformed bootable image; installing, from the virtual hard drive , a rolled-back operating system on to the automatic teller machine , the rolled-back operating system comprising the back-up system image of the client operating system ; receiving a patch that has altered the system update to create a patched system update intended for the client operating system ; and deploying, from the host operating system , the patched system update to the rolled-back operating system on the automatic teller machine . <EOS>
