FAQ for Moving Hard Drive to New Computer

Many people want to plug their old hard drive with Windows 7 directly into their new computer for convenience. But will this actually work?

This issue needs to be considered at both the hardware and system level.

Can you plug the old hard drive into new computer?

First of all, you need to make sure the new computer has a slot that supports the old hard drive. For example, if it is a PATA (IDE) drive and the new computer has only SATA, then you cannot just plug it in, unless you use a USB-to-PATA adapter or enclosure.

Will Windows still work if you move hard drive from one computer to another?

When you install Windows on your computer, it sets itself up with drivers specific to that computer's motherboard and chipset. Therefore, even if you create a full system image of the old hard drive and try to restore it to different hardware, you will very likely encounter errors about "hardware abstraction layer" or "hal.dll".

This is especially common in early operating systems such as Windows XP/Vista/7/8/8.1. To resolve it, you may need to use a backup and restore tool that supports dissimilar hardware restore.

Can you activate Windows 7 on new computer?

Even if the above two issues are ruled out, you should still consider license activation issues.

For OEM licenses that are pre-installed on the computer by the manufacturer, they are tied to the motherboard and can only be migrated with the same hardware; But if you are using a Retail license purchased from a local store or online retailer, it is possible to migrate between different hardware.
