Why choose bootable disk clone software?

As we move through our daily routines in computer use, we are often faced with all kinds of hard drive issues. Luckily, bootable cloning software can help us solve them. Here are advantages of bootable disk clone software.

  • Avoid low disk space and get better performance. After installing a lot of applications and programs on the hard drive, you are likely to get “low disk warning” from your PC. Then, the bootable disk clone software glowing, because it can help you replace the original hard drive with larger one. Usually, laptop only has one internal disk bay. In addition, long boot time, slow reaction speed, hard drive failure and so on may let you want to do the cloning for better performance.

  • Free you from reinstalling Windows. Boot drive cloning software will move everything including operating system on the hard drive to the target disk like SSD or bigger HDD. So when you want to replace or upgrade current hard drive with an OS on, there is no need to do a clean install of OS and all previously installed applications.

  • Keep your precious personal files intact. Most importantly, the system configurations and precious personal files such as family videos and childhood photos that you cannot create again will stay there. Also, you can access your data without booting Windows using bootable media created by certain professional software.

What kind of bootable hard disk clone software do you need?

Powerful cloning software should be able to perform different types of clone under different conditions. In a nutshell, the clone software for bootable hard drive should be embedded with these features.

  • Clone only used part of source disk to target disk, which is called Intelligent Clone. Since the old hard drive on your computer was purchased a few years ago and it cannot satisfy your pursuit of high performance, so you may want to replace HDD with SSD come to the market with advanced technologies, high price and low capacity. In this case, cloning old hard drive to a smaller SSD for replacement is inevitable.

  • Keep the same partition layout on target disk after cloning, which is called Sector-by-sector Clone. If you have enough budget and purchased an SSD, the cloning tool should allow you to keep the same partition layout of the old hard drive to the new SSD.

  • Partition alignment for SSDs during the process of cloning hard drive to SSD. SSDs have no moving parts compared to HDDs and you don’t have to defragment them. However, performing 4K alignment on SSD helps improve its performance. If you do not manually do 4K alignment, the computer will regard it as a cluster of 512 bytes through a method called Logical Block Addressing. That is not conducive to gain peak performance of SSD.

  • Clone between different partition styles. There is a chance that your source disk and target drive have different partition styles. You need a bootable cloning tool which enables you to clone MBR to GPT disk without disk conversion and vice versa.

Fortunately, the professional Windows bootable cloning software AOMEI Backupper Professional happens to meet all said requirements and provides more helpful features like Edit Partitions during clone, Partition Clone, Dynamic Disk Volume Clone, etc. It is easy-to-use software that requires no professional knowledge and skills. It even allows you to clone HDD with bad sectors effortlessly. 

Then, let’s have a closer look at the bootable drive clone software in the next part.

How to clone boot drive in Windows 11/10/8/7 with bootable disk clone software

If the operating system cannot boot or you want to clone boot drive without booting Windows, you can try this way. Note that you need to create the bootable USB on another PC if the system fails to boot.

Preparations: 

  • Prepare a USB flash drive (larger than 13GB) and make a bootable media with "Create Bootable Media" feature in "Tools".

  • Boot up the target computer with the bootable media. To clone hard drive to another disk, you need to connect the destination disk in advance.

You'll find AOMEI Backupper is pre-installed in that USB drive. Then, follow steps below to clone disk from the bootable USB. (If you have enabled the boot option of AOMEI Backupper recovery environment before system failure, you could start your computer from the AOMEI Backupper recovery environment and then create bootable disk clone as follows.)

Step 1. Click Clone and then Disk Clone. If you want to clone only OS, you can click System Clone instead.

Tips...
Checking Sector by sector clone will make Edit Partitions unavailable, but Edit Partitions is recommended when you clone disk to larger disk. That's because disk clone software will make an exact copy of original disk and leave unallocated space at the end. In this case, you need to adjust the partition size of destination disk with this feature.
 This software can also help you clone USB bootable drive, clone hard drive to larger drive, clone HDD to SSD via USB cable, clone Windows 10 to NVMe SSD, etc.
It's also a good backup solution which supports Incremental/Differential Backup and Daily/Weekly/Monthly Backup and so on.
If you’re a Server user, give AOMEI Backupper Server a shot.

Step 5. Shut down your PC on completion. Replace the original boot disk with the cloned drive carefully and restart your computer.

If you find the cloned disk cannot boot after cloning, take it easy! You can check boot order or boot mode (UEFI or Legacy) in BIOS, or visit cloned drive won't boot in Windows 10 for more details.
