Make data disk bootable (Intel NUC)

Installation Home Assistant OS
1

A few months ago I got tired of my backups filling up the disk so I got a NVME to put in my Intel NUC. I used the move data disk option to move everything over to the new disk. Everything has worked perfectly since then.

This morning I needed a SSD for another project and remember there was one sitting in my HA box that wasn’t being used anymore… You can probably guess the blunder I then made.

I pulled the SSD out and reformatted it for the new use. Sometime later I realized my HA wasn’t booting back up and discovered my mistake.

So, where do I go from here? Is there a way to make the NVME bootable? If I need to re-install from scratch how to I keep from loosing all of the data and configuration on the NVME?

I am proficient with Linux but am a Red Hat guy not Debian.

Thanks for any tips!

I took a chance and got it working again…

  1. Boot Fedora Live Image
  2. rsync contents of data disk to my NAS
  3. Use dd to write HAOS to data disk
  4. Rename the folders on the new data partition
  5. rsync contents back from the NAS to the data partition
  6. Boot it up
