Hi Cedirczhang The rescue process is expecting the SSD to not have a partition. (ie, no /dev/sda1) This tends to occur due to a partition existing on the SSD from the factory. Check if the SSD exists by running "lsscsi". If the SSD is not showing, please open a case with support for further investigation If the SSD does show from "lsscsi" then:Then check the partitions which exist "ls /dev/sd*"Also, In case the wrong model of SSD was installed as boot drive, Phoenix doesn't detect the SSD as boot drive and fails with the similar symptom. Hope this helps Thanks
