2 fit new sata hard drive to computer case using sata data and power cables or possibly a molex to sata power converter, making sure that the bios is set up correctly, and that the bios recognises the new hard drive on the first page when computer boots up.
3 install windows on new sata hard drive
I get to that point and then when I try to boot into windows I get the error 'Error Loading OS' and there's nothing I can do.
Even if I press F8 or whatever it is to get the boot selection and choose my SATA drive it still gives me the error.
