Please be careful with your question.
Meoboot and Openmultiboot are not the same plugins.
We did release a very beta version of Meoboot for OBH but it was quickly discontinued in favour of OpenMultiboot.
If you have any previously installed images (either Meoboot or OpenMultiboot) on your system (usb or hdd) then you should remove all of these from your devices, and then fresh flash (without any backups) with todays release.
Once you have a fully clean install, please try putting a freshly downloaded version of BH 2.1.6.1 into Openmultiboot and try again.
I have 12 images installed in OpenMultiboot on my Duo2 and all of them are booting just fine (including Bh 2.1.6.1 and VTi 8.2.2 which technically are the hardest images to make compatible with OpenMultiboot).
