Win7 setup format leaves unformatted HD unbootable

My computer has two drives, both 1 TB.

One has Win7 already, and was listed by the Win7 disk as primary.

The other drive, which has an older Win on it, I wanted to be wiped. It was listed by the win7 disk as system.

Because I could find no other convenient alternative to formatting (using disk manager didnt work, i would get an error JUST saying it could not be done), I booted off a usb drive containing win7 iso. From using the win7 setup, I selected the hard drive that I wanted to format, and went advanced driver options and selected format.

Afterwards, the hard drive that I wanted clean was listed as having full spaces available, while my main drive was unchanged in spaces available.

I quit out of win7 setup, and restarted, but the system would not boot from my main drive. Even removing my supposed wiped drive would not allow me to boot from my main drive. It was not a boot priority issue, it simply would not boot.

What happened, and what can I do


EDIT: To check the status of my main drive, I installed win7 onto the new drive which I formatted.

Booting up, I can see that my main drive that is unbootable still retains ALL of its files functional. However, it just cannot boot from it.

EDIT2: I have been told that in my case, the dual boot setup meant that my old windows hard drive held critical information for booting and operating my win7 hard drive. If this is the case, what can I do?

    That';s exactly what happened. If you want a seperate OS installed without mutli-boot, always disconnect all drives except the one you want the OS installed on.

    You might be able to fix it with a repair install, otherwise follow these directions.

    Worst case, you can always disconnect all drives except the one you want to boot from and reinstall windows onto it. Do a custom install so that you get the option to delete all old partitions if you want/need to.
  2. I am very thankful

    your method worked 100%


    I have a question though

    After repairing it, is my main win7 still reliant upon the other hard drive?
