I have built a new computer reusing some of my previous hardware including my hard drive but it is no longer drive c since i installed a new flash hard drive from which I now run windows. I have tried formatting from the disc manager and from the windows 7 ultimate install disc but it doesn't let me. How must I proceed to format it?
 
Solution
I tried booting from the disc in question, but it seems that the information on it was damaged and it will not boot, nor could windows repair it. How else can I proceed to format it?
