    I used clonezilla and will have to do it again. I cloned a 2tb to a 4tb and now Linux Mint says I have a 2tb hard drive. I would like to clone, but for Mint to report a 4tb hard drive. What did I do wrong?

    Hi, I ran into trouble with a clone (Macrium Reflect) of a Windows machine (7 updated to 8.1) dating from 2013. It seems the problem is related to the UEFI boot system (which can also make double-booting difficult for non specialists). The solution requires you to have boot from the rescue media, … which all of us think of preparing in advance and storing somewhere we can find it…
    I wanted to know if you might need a separate boot CD or key when cloning an exclusively Linux machine that has UEFI.
    It’s necessary to be quite clear about this for ordinary users, because though the best advice is always to test your cloned copy before putting it in the cupboard, people might be tempted not to do that because they don’t feel confident enough to open up and so risk damaging their computer.

      Clonezilla should do just fine even cloning a version of Windows. The problems occur only when the cloned disk is moved to other machine than the one being cloned, especially if you move the drive from a BIOS machine to a UEFI computer. All you need in order to use Clonezilla is just a CD image or a USB bootable drive to boot from. At the first screen of Clonezilla you even have the option to completely load it into RAM and remove the bootable media.

    I don’t really understand your issue? I’ve cloned a drive and placed it in a new machine, since you are mentioning something about a new kind o BIOS, i guess? When you install an OS (Windows, Linux or other), that OS is specifically tailored on your machine components. If you move the hard disk (or a drive clone for that matter) in a new machine, there’re chances that the OS won’t boot anymore!

    A couple of years ago I discovered to my cost that you could no longer boot a PC (Windows, at least) from a clone, because of some madness to do with the new kind of BIOS. The only solution was to make an image and a boot CD or USB key, and restore the image to the new disk. Please could we have an update on this situation?

      I recall a similar rule, one cannot perform sector to sector clones on Windows computer with GPT partitioning (UEFI). Believe that’s where Christopher Lee is coming from, one of the values (or partition identifiers) must be unique to be usable, though since I also use Macrium, have read some articles on this. Am not 100% for certain which of the partitions (probably one of the first three small ones) that MUST not be cloned sector to sector. Rather a ‘Smart’ clone that knows how to workaround the issue.

      However, the focus here is cloning Linux, is a non-dual boot, do these OS’s have the same partitions(s)?
