i'm not familiar with this tool and don't know what it does. is there some reason you cannot use the original Buster install media which has a rescue menu/option? adding someone else's idea of what the device should have on it aside from the Debian version sounds like a complicating factor which is usually not a good idea when trying to troubleshoot. > Of course, the safest thing would be to just reinstall Buster on sdd1.
