To move Windows 11 to another drive, such as a new SSD, you either clone the old drive to the new one, restore a system image onto it, or do a clean install and copy your files over. Windows 11 has no single “move Windows” button. The built-in System Image tool works without extra software, cloning tools are faster for most people, and a clean install gives the best performance but means reinstalling apps.
Which Method Should You Use?
- Clone the drive: the easiest way to keep everything exactly as it is. Needs a cloning app; many SSD makers provide one free.
- System image backup and restore: built into Windows 11, no extra software, but takes more steps and needs a third drive or large external drive to hold the image.
- Clean install: the fastest, cleanest result, especially when moving from an old hard drive. You reinstall apps and restore files from a backup.
Before You Start
- Back up your files to an external drive or OneDrive.
- Check space: the new drive must be large enough for everything currently on your Windows drive. Check used space in File Explorer under This PC.
- Connect the new drive: install it inside the PC (M.2 slot or SATA) or connect it with a USB enclosure or adapter. Then initialize it in Disk Management if Windows asks. See how to set up a new SSD.
- Suspend BitLocker if your drive is encrypted, so the clone or restore can boot without asking for the recovery key. Save the recovery key from aka.ms/myrecoverykey either way. More detail: how to remove BitLocker in Windows 11.
- Create a recovery USB drive or Windows 11 installation media; you will need it to boot for the system image method.
Method 1: Clone the Drive
- Download a cloning tool. SSD makers offer free ones for their drives, such as Samsung Magician (Data Migration), Crucial and WD editions of Acronis True Image, and Kingston’s Acronis edition. Clonezilla is a free, open-source option for any drive.
- Choose your current Windows drive as the source and the new drive as the destination. Double-check this, because everything on the destination will be erased.
- Let the tool resize partitions to fit the new drive if it offers that option.
- Start the clone and wait. It can take from minutes to a few hours depending on how much data you have.
- Shut down, then either remove the old drive or set the new one first in the boot order (see the boot drive section below).

Method 2: Use a System Image (No Extra Software)
Windows 11 still includes the older System Image Backup tool, though Microsoft no longer develops it.
Create the image
- Connect an external drive that is large enough to hold everything on your Windows drive.
- Open Control Panel, select Backup and Restore (Windows 7), then select Create a system image.
- Choose the external drive as the destination, make sure the system drives are selected, and select Start backup.
Restore the image to the new drive
- Shut down and install the new drive. Remove the old drive or disconnect it, so the restore cannot overwrite it.
- Boot from your Windows 11 USB drive. On the setup screen, select Next > Repair your computer.
- Select Troubleshoot > System Image Recovery and choose the image on the external drive.
- Follow the prompts, and select the option to format and repartition disks if asked. Windows restores everything to the new drive.
- Restart and remove the USB drive.
Method 3: Clean Install on the New Drive
- Back up your files.
- Create a Windows 11 installation USB with the Media Creation Tool.
- Install the new drive, boot from the USB, and choose Custom: Install Windows only.
- Select the new drive’s unallocated space and continue.
- After setup, sign in with your Microsoft account so Windows reactivates automatically, then restore your files and reinstall apps.

Set the New Drive as the Boot Drive
If you keep the old drive installed, make sure the PC starts from the new one. Restart, enter UEFI/BIOS setup (often by pressing F2, Del, or F10), and move the new drive or its Windows Boot Manager entry to the top of the boot order. Then boot into Windows and open Disk Management to confirm the new drive is labeled (C:) with the Boot partition. Once everything works, you can format the old drive and use it for storage.

Troubleshooting
The new drive is not shown in the cloning tool
Open Disk Management and initialize the drive as GPT. Check the cable or enclosure, and update the drive’s firmware or the storage driver.
“Inaccessible boot device” or the PC will not start
Make sure the BIOS is set to UEFI mode and the new drive is first in the boot order. If you cloned an MBR disk to a GPT system or the reverse, try cloning again with matching partition styles. Running Startup Repair from the recovery environment can also fix boot files.
The new drive shows unused space
Open Disk Management. If there is unallocated space after the C: partition, right-click C: and choose Extend Volume. If a recovery partition sits in the way, a partition tool may be needed to move it.
The system image will not restore
The new disk may be too small, or the old drive is still connected and selected. Disconnect other internal drives and try again.
Windows is not activated
Moving to a new drive in the same PC normally keeps activation. If not, go to Settings > System > Activation > Troubleshoot and sign in with your Microsoft account.
Frequently Asked Questions
Can I move Windows 11 to a smaller SSD?
Yes, if the data on your current drive fits on the new one. Most cloning tools shrink partitions automatically. System image restore is less flexible with smaller drives.
Will I need to reinstall my apps?
Not if you clone or use a system image. You will after a clean install.
Can I move only programs to another drive?
Store apps can be moved in Settings > Apps > Installed apps > Move. Most desktop programs must be uninstalled and reinstalled on the new drive.
Is cloning safe?
Yes, as long as you pick the correct destination drive and keep a backup. The source drive is only read during the clone.
