What You'll Need for Transferring Windows Boot Drive

To copy a boot drive, use disk cloning software to create an exact replica of your old drive onto a new one. After the cloning process, physically install the new drive, then enter your computer's BIOS/UEFI settings to set the new drive as the first boot device. To transfer the Windows boot disk to another disk, you need to make the following preparations:

• Buy the right SSD or HDD. To transfer a boot disk to another one, you need to have an HDD or SSD. You can have a hard drive from Samsung, Intel, Western Digital, Kingston, etc. Moreover, a hard drive with a capacity of 500GB is enough for ordinary use and future OS updates.
• Back up your data. Before you start, ensure you back up important files from your boot drive. This will ensure you have a copy of your data if anything goes wrong during the transfer process.
• Prepare one screwdriver and a connector. If your computer has only one slot, and, usually, most HDD drives use the SATA interface while SSDs have different interfaces, such as M.2, SATA, PCIe, NVMe, etc, confirm your disk interface and prepare a USB-to-SATA cable, adapter, or hard drive enclosure.
• Find reliable disk cloning software. As mentioned above, you must use third-party disk clone software like EaseUS Disk Copy, Clonezilla, or Acronis True Image to help you clone a hard drive.

After making these preparations, you can copy Windows boot drive to another.

Step-by-step guide to clone boot drive to another drive using EaseUS Disk Copy:

Prior Notice:

• The "Sector by sector copy" asks the size of your destination disk to be at least equal to or larger than that of the source disk. Leave this feature unchecked if you wish to clone a larger hard disk to a smaller hard disk.
• All data on the destination disk will be completely erased, so take care.

Step 1. To start copying/cloning an entire disk to another, choose this disk as the source disk under "Disk Mode" and click "Next".

Step 2. Choose the other disk as the destination disk.

Step 3. Check the disk layout of the two disks. You can manage the disk layout of the destination disk by selecting "Autofit the disk", "Copy as the source" or "Edit disk layout". 

• "Autofit the disk" makes some changes by default on the destination disk layout so that it can work at its best status.
• "Copy as the source"does not change anything on destination disk and the layout is the same as source disk.
• "Edit disk layout" allows you to manually resize/move partition layout on this destination disk.

Tick the "Check the option if the target is SSD" option to put your SSD in its best performance.

A message now appears, warning you that data will be lost. Please confirm this message by clicking "OK" and then click "Next".

Step 4. Click "Proceed" to officially execute the task.

How to Swap Boot Drives After Cloning

After the disk cloning process, you need to install the cloned hard drive on your PC because it will not automatically boot from the target disk. For a desktop computer, you can install the cloned drive alongside the old drive because it usually has more than one drive tray. You can change the boot order to set the cloned disk as your boot priority, and then it will boot.

For a laptop, the case is more complicated. You need to remove the old hard drive, install the new one, and then set the cloned drive as your first boot drive in the BIOS settings.

Here is an article about replacing the old drive and installing a new one.

The following is how to boot from the newly cloned drive:

• Step 1. Restart your laptop or PC and press the BIOS key to access the BIOS screen. The BIOS key depends on the computer manufacturer, but is generally F12, F2, Delete, or Esc.
• Step 2. Go to the Boot section using the arrow key, find the Boot Order or Boot Priority option, and choose it.
• Step 3. Top your cloned disk on the boot order list using the arrow key.
• Step 4. Save the changes before leaving the BIOS setup screen. When you reboot your PC or laptop, it will boot from the new drive.

Your computer should now boot from the new drive, which contains a complete copy of your old boot drive.
