I just got a new XPS 8900 today but when I start it up it won't boot Windows 10. It says "No bootable devices found".
I started it again, pressed F2 and brought up the settings screen. The only option under Boot Sequence is "UEFI: HL-DT-ST DVDRW/BDROM CH30N". But if I go to System Configuration-Drives it shows the 2000 GB HDD (ST2000DM001) as Sata-0, the BD-Combo as Sata-1 and the 256GB HDD (Samsung SSD PM851) as Sata-5.
If I reboot with "Windows 10 Pro 64-Bit" CD in the PC and press a key when prompted, it asks me for Language and then gives me choices for Troubleshoot or Turn off your PC.
In Troubleshoot, I tried Reset this PC and Recover from a drive but they all fail. I can provide the text here if need be. If I go into Advanced Options, System Restore and System Image Recovery boot fail as well. I can only choose Command Prompt.
The Command Prompt takes me to X:\windows\system32>. The only other drive I can find now is H: which has directories for boot, efi and sources. There was a C: drive earlier but it was empty. I looked around the internet and tried using DISKPART to clean C: and I think I made this all worse as C: no longer shows
Anyone have any suggestions how to proceed?
