We’ll focus on cloning first.
What You Need Before Moving Windows 10
Before you start, prepare the following:
✔ A new SSD or HDD
✔ SATA cable or USB-to-SATA adapter
✔ Backup of important files
✔ At least equal or larger target drive
✔ Cloning software
Popular cloning tools include:

- AOMEI Backupper
Most offer free versions.
Step 1: Connect the New Drive
If you’re using a desktop:

If using a laptop:
- Use USB-to-SATA adapter
- Or replace internal drive directly
Then:
- Press Windows + X
- Click Disk Management
- Initialize the new drive (if prompted)

Step 2: Clone Windows 10 to the New Drive
We’ll use Macrium Reflect as an example.
How to Clone Windows 10

- Select your current Windows drive (C:)
- Click Clone this disk
- Choose the new drive as destination
- Copy all partitions (including EFI and Recovery)
- Click Finish
- Start cloning
Cloning may take 20–60 minutes depending on drive size.
Step 3: Change Boot Order in BIOS
Once cloning completes, you must boot from the new drive.
To Enter BIOS:
- Restart your PC
- Press:
- F2
- Delete
- F12
- Esc
(It depends on manufacturer like Dell, HP, Lenovo)
Change Boot Priority
- Go to Boot menu
- Set new SSD as first boot device
- Save and exit
If successful, Windows will load from the new drive.
Step 4: Verify Windows Is Running from New Drive
After booting:
- Press Windows + X
- Click Disk Management
- Confirm new drive shows as C:
If yes — congratulations 🎉
You’ve successfully moved Windows 10.
Step 5: Format the Old Drive (Optional)
If everything works:

⚠ Only do this after confirming the new drive works perfectly.
Alternative Method: Fresh Install Windows 10
If you prefer a clean system:
