Hi
I recently upgraded my Dell XPS15 [9550]'s primary M2 NVMe drive and the machine had been working fine. I then went ahead and just added a second hard drive to the rig [usign the SATA 0 connection on the motherboard. On first boot initially, Windows 10 had no trouble booting up and Windows saw both drives. I went and deleted the Partition on the second drive [a 2.5 SSD], and went and formatted it, again no issues there. I did notice that it had an EFI partition which I didn't know why so I went thru a command prompt and deleted it/formatted the drive removing that partition. Again no issue as I hadn't rebooted...yet. Upon reboot, I receive the error message that there is no bootable device. I have removed the secondary drive and still have had no success booting back into windows. Any help would be appreciated.
