today I messed up my boot-configuration. It seems, as my bootloader was on one of my data drives, wich I just removed. So: No bootable drive...
I thought: No problem. Use super-grub-disk. So I ran the super grub disk and it successfully found my grub config and I was able to boot into my OMV system. Having this problem not the first time I ran "grub-install /dev/sde" (yes, sde.... don't ask) and it retuned no error. I checked the boot-flag on the partition /dev/sde1, wich was present so I thougt: Restart.
But: Still not bootable.
Do you have any suggestions?
