My Drive C has windows installed and all my programs. I have a 2nd SATA drive (Drive D) that I must have set up a long time ago as the bootable drive (I dont know why or how) -this drive does not have windows on it. Recently I formatted Drive D. Now my computer wont start! I have tried many solutions I've found from the net but nothing is working so far. Drive C shows as Active and Primary. Drive D shows as System, boot, Active, Primary. I have tried using Partition manager. I tried installing windows on Drive D in the hope I can then change the boot up drive to C. Tried startup repair. Tried DISKPART in CMD. Tried Bootrec commands but keep getting 'Element not found'. Any help would be really appreciated
