sda has three partitions. sda1, sda2, sda3.
sda1 is the boot partition that windows creates.
sda2 is where Windows, program files etc are.
sda3 is for my personal data.
something happened to Windows boot manager. The system would not boot (blank screen with a blinking cursor). I ran the following:
bootsect /nt60 all /force
Now I have the windows boot manager with an entry listed but it points to the wrong drive/partition. and /scanos does not pickup windows installation on sda2.
