    Hi everyone, I'm quite new to clonezilla, it's the first time that I'm might use it.

    I have a laptop with a dual boot on it like follows :

    image1

    image2

    I bought 2 new SSDs to replace them. A 2TB to replace the 512GB one, and a 4TB to replace the 2TB one.

    What is the best way to move and expand my dual boot system to those disk ?

    I want something a little bit like that :

    Disk 1 (2TB) : Windows C = ~800GB / Linux (/) = everything else : ~1.2TB

    Disk 2 (4TB) : Windows D = 800GB / Linux (/home) = ~2.6TB

    Thanks in advance for the help !

    The easiest way is you clone disk to disk one by one. Then use GParted live (gparted.org) to resize your partition size.
    //NOTE// Backup important data before you use Clonezilla and GParted. Just in case.

      But since it's dual boot, won't there be issues if I resize the Windows partition before Linux ? (Since it will make it start later than on the original disk). Like will I need to reinstall grub ? Will the whole install break ? And also I don't know if linux has hardcoded partition size or UUID in the system itself since I'm quite new to this ...

    "won't there be issues if I resize the Windows partition before Linux ? " -> Maybe.
    However, after you clone the disks, before you boot the machine, remember to remove the original disks from your PC. Then you can do whatever tests and modify on the cloned disks as you like. Nothing will lose since you keep the original disks.
    Normally you do not have to reinstall grub, and resizing with GParted live might keep the booting process OK normally.
    Just do it if you backup important data and keep the original disks.
