Hello, I have used openmultiboot for about a year on my VU+ DUO4K, latest BH image in the Flash booting automatically. There were 3 other images installed (VTi, OpenATV 6.3 and 1 other for testing) via Multiboot on internal SSD drive, used rarely for testing only. Yesterday I wanted to test new OpenATV image, original 6.3 was very old so I decided to install 6.4 and delete the old 6.3 version. Installation went fine, OpenATV 6.4 appered in the OpenMultiboot menu and old 6.3 was deleted. But after reboot the 6.4 version is stuck on OpenATV logo and nothing more is happening. Off course the image selection on start is disabled so I don't know how do I return to my BH image and remove this OpenATV 6.4 from booting via OpenMultiboot. Can anyone advice how to disable/remove non-working image selected for booting? I don't want to completely format my SSD and install all from scratch... Thanks a lot for help.
