Hello, your solid state drive is faulty, so if you don't want loose your datas on your SSD you need to backup it on your other hard drive, or (the better) in an external drive, by copy/paste.
And for reinstall Windows if you need to replace the SSD, you need use the software HP Recovery Manager if it is on your PC to create an external media to reinstall Windows.
