I just purchased a new hard drive that has 160GB, if I remove my existing hard drive "C" and replace with the new one, how I will be able to resstart my computer, The mechanics on how to change drives I know, the question is how the computer will resstart. I have backup the entire drive "C" on an external drive. I need some help. I adition I do have a separate drive that I call drive "G", but the main drive is "C". Thank you :roll:
