If this was a Duel Boot ( MacOS and Win XP ) shutdown computer. Start computer and Immediately hold the OPTION key. This should bring up the BootManager. It will present the option to boot to macOS of Win XP.
if, Win XP was installed as the Only OS and the macOS Recovery Partition was erased - it will require access to another Apple computer to download and create a Bootable Installer that is compatible with the Model of Apple Computer you are using
