I have been experimenting with cloning dual boots, with mixed success.

Acronis True Image successfully will clone a Windows 10 installation, but all Linux (Ubuntu base) OS's are broken.

Similarly, when using Clonezilla, and later dd to clone, the Linux partitions boot properly, but Windows throws an error.

Feel free to assume the drives are the same size, but honestly bonus points if it supports cloning to different sized drives.

Thanks!! Been trying to crack this nut for years.

Acronis True Image successfully will clone a Windows 10 installation. So that is done.

You can clone your Linux partitions with GParted. Boot a 'Live'-USB and clone the partitions. Resize if needed/wanted. Your partitions will have other UUID's (to know the UUID use GParted), so you need to adjust the following files:

• fstab (found in /etc)

• In etc/grub.d you need to modify your 10_linux_proxy file and 30_OS_prober (for your Windows OS). Then do a sudo update-grub.

• Another UUID to change is the in the EFI-partition (/EFI/ubuntu/grub.cfg).
