Cannot boot win7 (bootcamp) after updating to high sierra

Hi there.

Today, after updating to high sierra I haven't been able to boot into my win7 bootcamp.

While holding 'alt' it does show both, but after getting to the blinking '-' it doesn't get any further. Usually it took around 1-2 minutes for it to show windows startup graphics but now it just keeps going. Tried letting it continue around 15min but nothing happens. In OSX I can still see the BOOTCAMP partition under 'devices' in finder and the files still seem intact.

Anyone else experiencing this?

Maybe someone has an idea of what is happening?

Kind Regards
