Apparent problem 1 - your hard drives aren't showing up when you boot. Problem 2 - you can't boot from your DVD drive. It's anything but obvious what the connection between these two is. Normally you'd boot from the Windows 7 DVD and it would identify your drives and tell you whether they're formatted or not. What happens when you do this? Or are you doing this? Have you formatted the new drive? NTFS or GPT? The answers you get are only going to be as good as the info you provide!
I have a Dell Dimension E521.
I purchased a new HDD and a Windows 7 Professional (for new PC) DVD.
My problem is that my internal DVD drives do not show up as an options in my boot sequence list.
Both drives were available when I have my Vista HDD in the machine.
How can I Boot from my DVD drive so I can install the new operating system?
Thanks.
