If an affected system is rebooted, it might not come back online. Instead, the [serial over SSH](https://metal.equinix.com/developers/docs/resilience-recovery/serial-over-ssh/) or SOS console will show the system at the GRUB prompt.
To recover from this condition, log in to the SOS console, which will connect you to GRUB. Then issue the following command:
```
grub> configfile ($root)/EFI/GRUB/grub.cfg
```
The device will load the correct boot sequence and return to service.
