Hello All, My F16 box which has given me years of faithful service has unexpectedly failed to boot. I made no configuration changes or updates yesterday and the system worked fine. Today the system fails to boot with the error: error: no such device: 53d08854-7c6d-49dc-aeec-6a5d3e462682. Entering rescue mode... Grub> The little Googling I have been able to do on my phone brings up examples of that error when people have upgraded or attempted to upgrade over an existing system. Mine has come out of the blue to a working system. I am very nervous of the risk of causing more damage by incautious tinkering (my usual method of trying to fix problems) so I thought I would ask here before I tried anything. Can anyone guide me through troubleshooting and hopfully fixing this without hosing my system?
