I upgraded a Vista PC to Win7 with no problem. Next day I powered up and the profile records were corrupted; I booted safe using inbuilt Administrator but could not get into Control Panel - presumably the same corruption.
Fortunately I had just taken an image of the Vista disk so I restored that. Now I was getting a black screen after BIOS and before Windows logo. I booted off a Linux CD with no problem. I booted off a Windows 10 installation USB pen drive with no problem.
I figured the disk must have gone South like Sherman so I restored my image to a different disk - now I get 'no bootable device'. I switched the SATA cable and port on the mobo - same problem. I tested the voltages at the plug to the HDD but they were fine.
Ok so I must have a fault on the SATA circuit on the mobo. I installed a PCIe disk controller and attached my disk to that. The controller reported a functional JBOD but when it went to hit that thing... 'no bootable device'. It was then that I turned to Google and was prompted to reset the BIOS to defaults so I pulled the battery for 20 minutes. When I reset the date and booted again: 'no bootable device'.
Now I'm fresh out of ideas and asking for some suggestions.
