arkhi Posted March 18, 2023 Share Posted March 18, 2023 (edited) Hello, I’m in a pickle. I bought an Odroid HC4 a few months ago, setup a RAID-1 array and installed Nextcloud on it. At the time, I used `nand-sata-install` to move the system from the SD‑card to a partition of one of the HDD (/dev/sda1), out of RAID (/dev/md0), and leave the bootloader on the SD-card. I did not make a backup of this SD-card and, after rebooting today, I realised the SD-card was not functioning any more. No device I use (Sansa audio player with Rockbox, phone with Ubuntu Touch, Laptop with Ubuntu) would even detect it. I was thinking of using `nand-sata-install` again to only update the bootloader on the SD‑card but I’m afraid it will overwrite what is already on /dev/sda1 instead of only pointing to it. So here are my questions: 1. Would you know if `nand-sata-install` can be used safely to recreate the bootloader on the SD‑card without touching anything else? 2. Is there a manual for this tool, or are you able to explain how this would work? 3. Otherwise, is it possible to only copy a few files manually to the SD‑card to get the same result, and maybe update a few variables in some files? Thanks for any solution or pointer, I’ve searched on this forum and in other places without success so far.
