How to Clone GPT Disk to SSD or MBR Safely in Windows 10
Overview of GPT disk
The GUID Partition Table (GPT) is a new standard for storing partition information on physical storage devices, such as hard drives or solid-state drives, offering a more flexible disk partitioning mechanism. This allows the operating system to identify which sectors belong to each partition and determine which partition is bootable, making it a more efficient and organized way to manage storage.
Besides the newer partition scheme, GPT disk, there is an older version, MBR disk, which also partitions a disk. However, there are differences between the two.
- Differences between GPT and MBR:
- Boot modes: UEFI firmware allows a computer to boot from a UEFI partition, while Legacy BIOS firmware is limited to booting from a Master Boot Record (MBR) partition. This means that a computer with UEFI firmware can boot from a UEFI-based operating system, such as Windows 10, while a computer with Legacy BIOS firmware is limited to booting from an MBR-based operating system, such as Windows XP.
- Partition numbers: GPT disks allow for more partition flexibility, supporting up to 128 primary partitions, whereas MBR disks are limited to 4 primary partitions or 3 primary partitions and 1 extended partition.
- Disk capacity: GPT disks have a much larger maximum hard drive size compared to MBR disks. While MBR disks are limited to a maximum size of 2TB, GPT disks can support sizes exceeding 9 Zettabytes (ZB).
- Processor: A GPT disk can only be installed on 64-bit systems, whereas a MBR disk supports both 32-bit and 64-bit systems.
Can I clone a GPT disk as an MBR?
You can clone a GPT disk as an MBR disk, but it requires a different approach. Unlike MBR disks, GPT disks can have multiple primary partitions and are more flexible. When cloning a GPT disk to an MBR disk, you'll need to convert the GPT partition table to an MBR partition table, which can be done using some disk management tools.
Cloning a disk, whether it's MBR or GPT, requires disk cloning software. If the target disk is a GPT disk, it's essential to ensure it has the same or larger capacity. If not, you can either delete unnecessary files, uninstall programs, or use software that only clones used sectors. This will help you successfully clone your disk.
If the target disk is MBR, To clone a larger disk to a smaller one, you need to convert the target disk from MBR to GPT, which involves deleting all data on the target disk and has limitations in cloning primary partitions. This process can result in data loss or boot failure if not done correctly.
Best software to clone GPT disk in Windows 10
Since Windows itself does not have a disk cloning feature, you can try Qiling Disk Master Professional, a powerful and easy-to-use disk cloning software that can clone a GPT HDD to SSD or MBR, with features such as cloning HDD/SSD or MBR/GPT of different brands or interfaces.
- Intelligent Clone: Clone only used sectors of selected partition or disk, allowing for easy cloning of a GPT disk to a smaller SSD.
- Convert the destination disk from MBR to GPT: It allows you to convert the disk partition style from MBR to GPT if the target disk is an MBR, making both disks GPT and enabling successful booting after cloning.
- Edit Partitions allows manual or automatic adjustment of partition size on the destination disk, particularly helpful for larger drives.
- SSD Alignment: The technology can further enhance the reading and writing speed of SSDs, as well as extend their lifespan.
To get started, download and install the free trial, or for server users, try Qiling Disk Master Server.
How to clone GPT HDD to SSD or MBR in Windows 10 safely
Before cloning, you'll need to make some preparations.
- Before cloning, make sure to backup all your important data to prevent loss in case something goes wrong during the cloning process. The target SSD or MBR will be completely erased and all data on it will be deleted.
- A connector for cloning is required, which depends on the disk interface, such as SATA, NVMe, PCIe, M.2, etc. This connector is essential for connecting the source and target disks during the cloning process, ensuring a seamless and efficient transfer of data.
- If the target disk is a smaller SSD, freeing up disk space can be beneficial. This is because smaller SSDs have limited storage capacity, and deleting unnecessary files and programs can help make more space available for essential data and applications.
Step 1. To clone a disk, connect the SSD to your machine via a SATA-to-USB cable or install it directly. Then, open Qiling Disk Master Professional, click on "Clone", and select "Disk Clone" from the options.
Step 2. Select the UEFI GPT disk you want to clone as the source disk and then click Next.
Step 3. Click on the destination disk (GPT or MBR SSD) and Next.
Step 4. To improve SSD performance, check the SSD Alignment and consider editing partitions to resize and convert the disk type on the destination disk, then proceed with the clone process.
Cloning is the most effective method for upgrading a hard drive, but it's not suitable for migrating Windows 10 to a new computer due to hardware differences between machines.
To transfer Windows 10 to a new computer, create a disk backup in Windows 10, then restore the image to the new computer, ensuring the " niversal Restore" feature is checked to avoid restore process failure.Universal Restore" feature is checked to avoid restore process failure.
For multiple computers, consider using image deployment software in Qiling Disk Master Technician or TechPlus edition, which allows you to deploy system images to unlimited PCs or servers without installation, and offers billable service to unlimited clients.
Tips on how to boot from cloned SSD:
After cloning, reboot your computer, tap a specific key (usually Del or F2) during boot-up to enter BIOS, and set the SSD disk as the primary boot device.
If your target SSD is still in MBR mode after cloning, you'll need to change the boot mode as well. To do this, go to the Boot mode section and disable UEFI boot, then enable Legacy boot. Save the changes and restart your computer.
If your computer is not bootable, you can try making a cloned drive bootable in Windows 10. To do this, you'll need to create a bootable USB drive or CD/DVD, and then use a tool like Rufus or a similar software to make the cloned drive bootable.
Summary
You can easily clone a GPT disk in Windows 10 using the Qiling Disk Master Professional, a top-notch disk cloning software that can handle the differences between GPT and MBR disks.
AOMEI Backupper allows you to convert the destination disk from MBR to GPT, eliminating the risk of boot failure due to different disk partition types. This feature provides a safer way to upgrade your hard drive, making it a useful tool for those who want to upgrade their hard drive without worrying about compatibility issues.
