I have 2 drives on my old machine: C & D and despite my windows 10 installation on C drive, it was an upgrade from the old Windows 7 which I installed on my D drive before. Now that D drive is broken so I bought new hardware and tried to bring my C drive to the new box, its BIOS would not see it as a bootable device despite it\’s primary partition is active. Is it because of the missing windows bootloader? Is there a way for me to put Windows bootloader on my C drive so it can be started up? TIA
In BIOS, point to C: drive to boot. Right now, it’s pointing to D:. Have you tried this?
