Case: transfer Windows 7 to new hard drive without CD

 

Hi everyone, I have a hard drive with a disk read error. It has Windows 7 installed and I can't locate the installation CD anymore. I'm thinking about buying a new SSD, but the problem is I don't want to buy another Windows 7 again. Do I have an option here without having to buy a new license?

First, the answer is YES. When a hard drive goes wrong or performs poorly, you can upgrade it to a new one (like replace HDD with SSD) to boost performance.

Don't want to lose data or re-purchase a license? Try to transfer Windows 7 to new hard drive without CD and reinstalling. Usually, the license key can be used on the same computer when you transfer Windows 7 to new hard drive, even for OEM license.

Transfer Windows 7 to New Hard Drive Without CD

How do I transfer Windows 7 to new hard drive without CD?

To implement the system migration, you can either backup & restore system image, or directly clone the system disk to a new hard drive, whether it's SSD or HDD.

Backup and Restore:  It will compress all the content of a system partition or disk into an image file, and requires a storage device to store backup image temperarily and restoration before booting from it. If the computer is not bootable, you still need to create a bootable USB or CD/DVD with it. 

Clone: It will keep the original structure of system partition and disk, no image file, extra device and restoration. The bootable media is required as well if the computer fails. 

Well then, which one should you use? If you don't know how to choose between them, please refer to the following contents. And either way, try corresponding methods for system ( to migrate OS only) and disk. 

✍ If your computer only has one slot or it's a laptop, try backup and restore method.
✍If you want to transfer Windows 10 to new computer, try backup and restore method. Its Universal Restore feature is able to resolve different hardware issues between computers.
✍ If you just want to upgrade hard drive or boost computer performance, try cloning method.  And the operation is much easier.

Migrate Windows 7 to new hard drive step by step 

By now, you may have chosen one of these methods and jumped at the chance to try it. Please make some preparations in advance to ensure the target SSD is bootable after restoration and try the following method based on your needs. 

Preparations before operating system migration

Before starting, there are a few things you should do at first:

1. Clean up the current system hard drive.

You could delete some junk files, uninstall rarely used apps to lighten your system so as to speed up the transferring. But please don't move or delete those system files you are not sure what they are.

2. Connect the target drive.

Make sure the new SSD or HDD has enough capacity for the operating system, and install it alongside your old drive. If there's only one slot on your computer, you can use a USB-to-SATA adapter to connect it.

3. Pick an efficient system migration tool.

Though Windows has a Backup and Restore utility, the steps for system migration are complicated, and it requires an installation or recovery disk to restore system image to the new hard drive. So it is more recommended to use freeware like AOMEI Backupper Standard.

It enables you to transfer Windows to new drive by restoring or cloning, and greatly simplify the operation. You can download and install it to have a try. For server users, try AOMEI Backupper Server.

◆ If you want to transfer Windows 7 to another computer with dissimilar hardware (such as installing OS on new PC, physical to virtual migration etc.), you can tick Universal Restore to ensure the comptuer can boot after restoration. 
◆ If you want to restore an image file to new hard drive without booting Windows, you may create recovery environment with AOMEI Backupper in advance.

Way 2: Clone disk with Windows installed to new hard drive

Disk Clone is a more intuitive way to transfer Windows 7 to new hard drive without CD and it will include everything on the disk. With it, you can directly clone a disk instead of creating backup image and then restoring. To only clones the system and boot related drive, try next method.
