How to Clone A Computer System and Boot from It Successfully
Why we need to clone a computer system?
How to clone a computer system? This may be a question when we need to replace a new disk. In ordinary life or work, we choose to clone a computer operating system for the following reasons:
✐ The aging of computer hardware such as motherboards, graphics cards and other devices makes you no longer able to use it. But you are very satisfied with the current operating system, so when you buy a new computer, you plan to clone the old system to the new computer for use.
✐ If you want to upgrade HDD to SSD to improve the performance of the computer, you can clone the Windows system to SSD without reinstalling.
✐ Clone the system to an external hard drive for backup.

How to boot from the new disk after cloning
After you clone a computer system to a hard drive, you need to put the new disk back and change the boot sequence in the BIOS menu to boot Windows 11/10/8/7 from the new hard drive.
1. Keep pressing F2, F3, F4, F5, ESC or other keys to enter the BIOS menu when the computer starts.
2. In the BIOS menu, choose "Enter setup"
3. Choose "Change boot order" in the "setup" utility.
4. To make the cloned hard drive take precedence over other hard drives, move it to the first one.
5. Save the changes and exit the BIOS setup utility. The computer will restart.
What to do if it does not start after cloning?
If you want to use the newly cloned hard drive in the same computer, you should pay attention to whether the hard drive is an MBR hard drive, because you need to set the boot mode to Legacy/CSM boot mode. If Windows 10 is cloned to a GPT hard drive, the motherboard not only needs to support EFI/UEFI, but also set the boot mode to EFI/UEFI boot mode. Otherwise, the computer cannot start from the drive.
Finally, if you clone the computer system to a new computer with different hardware, your new computer may not start normally. Because when you first install the system on the first computer, Windows will set itself according to the motherboard device, chipset, CPU, etc. of the PC. For the second PC when the operating system is moved, Windows may not run successfully due to various hardware differences.
Fortunately, Universal Restore allows you to restore the operating system to a computer with different hardware. Therefore, you can immediately restore the operating system and deploy the same operating system to multiple computers in the event of a hardware failure.
