Installation and update

Installation process

The installation of the package Boot-US is a two step process:
  • Installation of configuration program Boot-US (GUI)
  • Installation of boot manager
You first install the configuration program. This is a standard Windows installation. Then you use the configuration program to install a current version of the boot manager. You can use the configuration program also to access a previous version of the boot manager. All configuration programs can read the data of all previous boot manager versions.

The installation of the configuration program does not change the boot behaviour of the machine. Only the installation of the boot manager changes the boot behaviour.

If you have multiple Windows installations on your machine you can install the configuration program on each Windows installation. This allows you to access the boot manager from each Windows installation. The boot manager itself is installed only in a single instance on the machine.

It is not required to uninstall the old version before an update.

The update of the boot manager to a new version is a two step process:

  • Update of configuration program Boot-US (GUI)
  • Update of boot manager
