Multiboot USB with rEFInd x86_64 UEFI

Multiboot USB with rEFInd (Please star it if it helps you!!!)

This gist is for x86_64 (amd64) architecture and UEFI boot mode!

Suppose you have 3 partitions: 1. EFI partition (FAT32); 2. macOS partition (Mac OS Extended); 3. WinPE and multiple Linux distros partition (FAT32).

1. EFI partition should have: a. rEFInd's files: bootx64.efi, refind.conf and icons folder; b. WinPE's boot files: bcd and bootx64.efi (bcd file needs to be modified according to your WinPE's boot.sdi and boot.wim)

2. macOS patition should have your macOS image file.

3. WinPE and multiple Linux distros partition should have different folders to include the ISO and their bootloaders. Normally, bootloaders for linux distros can be extracted from their ISO files, but some Debian based installers (Debian and Kali) need to be downloaded from their corresponding mirror sites, e.g. https://mirrors.XXX.debain.org/debian/dists/Debian11.1/main/installer-amd64/current/images/hd-media/.
