Judging from the title, many people may know how to do it, but there are pitfalls in the process. I only did it last night, and now record it and share it with friends in need.
My hard drive is as follows:
| HDD 1 | HDD 2 | HDD 3 |
| C | D | E、F |
| 128G | 512G | 2t |
The time of use and the amount of software installed at any time increased, and the space of hard disk 1, that is, the C drive was getting smaller and smaller, only 2G. However, due to the large amount of installed software, I had a deep fear of reinstalling the system, so I thought about using a larger hard disk to replace the current 128G hard disk. In order to keep the content consistent, use DiskGenius hard disk copy method.
1. Prepare a U disk, download Lao Maotao from the Internet, and use this software to make the U disk as a system boot disk.
2. Use the U disk to boot to the PE system (here, it should be noted that most computers do not start from the U disk when the U disk is plugged in. You need to select the startup disk. Older computers can press F9 or F11 to pop up the startup disk when starting up. Every computer is different. Mine is an Asus motherboard. You need to press F2 to enter the BIOS and then press F8 to select the startup disk. Sometimes you have to turn off Quick Start in the BIOS, and do not display the LOG to see the key prompts)
3. Start the DiskGenius software, select "Tools/Clone Hard Disk", select the source disk and target disk in the pop-up dialog box, and then start (because this article is written on the company computer, there is no screenshot).
4. After hard disk cloning is completed, shut down the computer first, then unplug the original hard disk, and keep the cloned hard disk. Don’t be curious about booting up with two hard disks plugged in. After booting, the original hard disk will be marked as a boot disk because there are two identical hard disks. When you unplug the original hard disk, the newly cloned hard disk will not start. My prompt is "c:\windows\system32\winload.efi is missing". Later, my solution was to clone again, and after cloning, I unplugged the original hard disk cable, so there was no problem.
5. Use the cloned hard disk to enter the system, right-click "My Computer/Management/Disk Management", right-click the C disk, and select "Extend Volume", then you can give the extra space to the C disk, so that the entire hard disk space will be more (I directly replaced a 1T hard disk as the C disk, which should be enough now!)
