I have created a Golden image file of three partitions (EFI, root, swap) using the existing Debian OS (Installed on USB stick) with the dd command.
After successfully creating the mender artifact I got 4 files in deploy folder having extention as (.img, .mender, .cfg, .ext4)
Created a bootable USB stick using .img file and booted on machine.
But after booting screen is stuck on Grub prompt.
Any help would be greatly appreciated.
