For some reasons I decided to do a new install at first I ran into grub was getting an other drive like this thread mdadm: no arrays found in config file or automatically I fixed it by following couch_potatozes advice
I was making sure I did update grub,
booted several time no problem, but now out of nowhere getting "no boot device found" so how can I fix it since I do not get the grub blue screen anymore ?
