A longer version is available here: How to clone your hard drive with Clonezilla.ġ. However, to help out, we've put together a short guide below on how to use it. To clone a disk including a Windows system, the disk style (GPT/MBR) of the source disk and the destination disk must be the same. However, do note that the free standard edition only supports a data disk clone. Instead, there's a paid-for version available from $39.95 for a single PC license. The whole process means that you end up with a full copy of your harddrive and won't need to reinstall Windows when copying your clone over to a new harddrive. Although the software is Freeware, there's no adware bundled with the software.
There's also an intelligent cloning option, which only copies over used space on the harddrive. Sectors and partitions are copied over, along with key files such as boot.ini, NTLDR, BCD, winload.exe and MBR. A key feature of the software is the ability to clone a large disk to a smaller SSD drive.
AOMEI Backupper is a disk cloning utility that's free to download and use.
