Your boot device has failed. Reinstall the same version to a new boot media and restore your previously saved config.

Thank you for your reply.I have used the u disk to reinstall the system on the original ssd, but still show this error.

That won't help if the original SSD has failed, which is probably what happened. You will need to install to a new boot device.

But original ssd can still start normally, just jump out of alerts.ssd itself is not bad, just the system has a problem

This part means that you have some corrupt sectors on the boot device. This is usually an indication that the drive will soon fail completely. You should not ignore this warning if you care about your system and your access to the data on it (the data should remain safe in any case).

The replacement of a boot drive (particularly if it's just a USB stick) is easy and relatively risk-free as long as you're doing it as part of a plan.

I recommend replacing it as soon as you can.
