We are using the EPCR2860NQEW-ES (ROM2860, based on QCS6490), and as part of our standard procedure, we attempted to back up the internal disk using the third-party tool AOMEI Backupper Standard, downloaded from the official website.

However, after installing the software and rebooting the device, we encountered a blue screen error: INACCESSIBLE_BOOT_DEVICE, and the system has since failed to boot, even after multiple power cycles.
We would greatly appreciate your guidance on how to recover the system from this error.
