System is an Acer L4620g, was running Windows 7 Pro, upgraded to Windows 10 using the Media Creation Tool to upgrade this PC. (RAM 8Gb; Processor i5-3330s; SSD 250Gb)
Before the upgrade the system was working fine. After the upgrade as long as the system was restarted it would come back to the desktop correctly. Upon the first actual Shutdown however, the system boots only to the black and white screen with the above message about no boot disk.
In the BIOS it shows that a Samsung 860 EVO 250Gb SSD occupies the SATA 1 slot; the first boot device is set to the Hard Drive option; Legacy or Secure Boot has made no difference; if the SSD is removed and taken to another computer (same make and model) it realizes that it is in a new machine and boots up to the 10 desktop; upon shutdown however it comes back to the same message; if then returned to this system it boots up once and then repeats the issue after shutdown.
Installing Windows 10 anew is not the preferred option due to the applications already installed on the computer.
We have tried a clean install of Windows 10 and it works correctly, so we can rebuild fresh if we have to but that is not preferred.
Primary suspect is the boot sector. Have tried rebooting to Windows 10 USB Media and repair the drive, no joy; have tried rebuilding the MBR with bootrec.exe, no joy; while awaiting any replies we are going to try rebuilding the MBR with other tools.
If the overall consensus is to simply perform the new install and move on, we will, but again it really isn't desired.
Other MISC:
Updated the BIOS to the latest on the Acer website for this model, no joy;
Tried imaging the SSD to a standard HDD, no joy;
Moved the hard drive to a completely different Acer machine (X6630g), same issue, no joy;
