Re: upgrading to new computer
Sometimes a computer doesn't come with a restore disk. It comes with the restore data on a partition, or D: drive like you said. If it didn't come with a disk, too, there should be a program in your start menu from the manufacturer of your computer that lets you make restore disks. You need to find this program and make restore disk(s), then boot to that disk and do what it says to restore your computer. In order to boot to a CD/DVD, you may need to change your boot sequence in the BIOS so that your 1st boot is CD and your 2nd boot is the main hard drive. Someone already mentioned that.
If you uninstalled the manufacturer's program to make a restore disk, you'll have to go to their website and hope they have the program available to download. If you happened to erase your D: drive to use it for extra storage, you're screwed. If that is the case, you have a couple of choices. You can go to the manufacturer's website and see if they have a restore disk available for your computer, which will cost you money and time waiting. Or you can manually go to add/remove programs and remove everything you installed, go to Windows Explorer and delete every file you have put on your computer, then go to your Internet Options and delete all cookies, history, temporary files, saved passwords, and web form information. Make sure you empty your recycle bin, too.
