Dual Boot macOS / zorinOS / Clonezilla recovery using rEFInd (iMac 2015) Overview & Hardware Target This guide provides a complete walkthrough for setting up a reliable triple-boot configuration—consisting of macOS Monterey (12.7.6), Zorin OS, and a self-hosted Clonezilla Recovery environment—managed by the rEFInd boot manager. This specific deployment is engineered for Late 2015 Retina 5K 27" iMacs (Apple17,1) with an Intel Core i7 processor and AMD Radeon R9 M395X graphics. This hardware suffers...

I built a clean, hardware-agnostic Recovery Wizard that works from the USB itself — both RESTORE and SAVE — without any hardcoded device names. How it works (the flow) GRUB dynamically finds the USB with search --set -f /live/vmlinuz and captures its permanent FAT32 UUID with probe -u $root --set=usb_uuid. The UUID is injected into ocs_prerun1 so Clonezilla can temporarily mount the USB, copy script.sh locally, then unmount. The bash script parses the exact same UUID from /proc/cmdline using a simple...
