Clonezilla and the Curious Case of macOS-Windows10 Dual Boot

Clonezilla is awesome and I have used it on all my laptops for many years and it has saved my life many times. A few months back I decided to make my Asus laptop a dual boot machine with macOS Mojave and Windows 10 (for certain app development work, I need both). To save many hours of work to make the dual boot work, I promptly saved a disk image through Clonezilla.

I have 3 partitions on the HDD:

  • EFI partition - houses the clover bootloader + possible other stuff
  • macOS APFS partition
  • Windows10 NTFS partition

So now when I boot the laptop, the BIOS sees 2 boot options :

  1. Clover bootloader
  2. Windows 10

Ofcourse, I choose the Clover bootloader and from there I can go to whichever OS I want to work in. This has worked great for months and I dont have a problem with it.

The problem arises when I attempt to "Restore disk" with the previous dual boot full HDD image that I had created above. After the restore, BIOS can only "see" the windows partition and can safely boot into it. But, it cannot see the Clover bootloader option, so I cannot get into clover. Please advise ?

FYI, when I restore the disk image containing only macOS (i had created that before I was even able to make the dual boot work) , I face no problem and clover pops right up after the Clonezilla restore.
