First of all, I would recommend you copy the virtual disk image
somewhere else, in case the attempts to fix things causes some
bug to delete or corrupt it.

If you are using "bare" qemu (i.e. running the qemu-kvm or
qemu-system-x86_64 program yourself), then simply running qemu
again with the boot virtual disk in it's proper place will fix it,
because qemu itself doesn't remember anything from one run to the
next.

If you are using libvirt to run qemu, use "virsh edit" to manually
edit the configuration file of a "not running" virtual machine to
bypass the UI automation that may be getting in the way of
connecting an existing virtual disk image where you want it.

Enjoy
