Patent attributes
Disclosed herein are systems and methods for deploying and/or rolling back automatic teller machine (ATM) updates. Such methods can store a back-up system image of a client operating system on a virtual hard drive. When an update is deployed from a host operating system to the client operating system, the system update may fail to install properly, and the ATM may shut down. In response, the host operating system can execute instructions to the client operating system to boot from a bootable image on the virtual hard drive. Then, the virtual hard drive can emulate, by a boot loader on the back-up system image, the client operating system on the ATM from the virtual hard drive without loading the client operating system. Then, the virtual hard drive can install a rolled-back operating system on the ATM. The rolled-back operating system can comprise the back-up system image.
