My laptop bluescreened last night. When it rebooted it couldn't see the SSD which has Windows on it. Startup just gives an 3F0 error with the message "Boot device not found". I tried troubleshooting - hard reset, disk check, all the repair options I could find. I even took the back off and reseated both drives.
The diagnostics only saw one drive (the HDD), which passed all the tests (but isn't bootable and doesn't have an OS on it).
The "HP System Diagnostics UEFI or HP UEFI Support Environment" could see the SSD (run from a USB stick, with the HDD removed) and it passed all tests, but it seems that UEFI can't connect at all to the SSD. The restore to factory settings won't even work, because I can't get it to see the SSD which has Windows installed.
Any help or ideas much appreciated!
