Whats the easiest way to make a multi-boot UEFI Windows/Linux/Mac (Universal) DVD/BD?

Question

I can find tons of programs to make such USBs, but some computers I work with (like an older netbook) won’t boot specific OSs from USB.

But I want to fill up a BD ROM disc with various forms of Linux, Windows, Android x86 and recovery tools... Where do I start?

Answer 1

I'd recommend YUMI - Your Universal Multiboot Installer. Granted this is made for a USB drive, but then use the same as above - I can't say for sure it'll work, but I think it will. You will need a USB drive (or blank partition) to install the GRUB files. Works with Windows and a bunch of other Linux installers and live CDs.

To create an ISO from a USB drive, you can use a tool like the one mentioned in the Hak5 forum

Answer 2

The easiest way based on what you already have is likely:

1. Create the USB version
2. Create an ISO from that USB
3. Burn the ISO to the disc

That said, if they don't support booting from a USB, I highly doubt they will support booting from a BD.

Answer 3

Much time later...

I discovered the easiest way.

1. • Format USB as FAT 32.
2. • Use Winrar, 7zip to extract EFI capable ISO to Directory. (Like a windows 7/8/10 disk) (or a Linux Disk) [NOT a MAC Disk]
3. • Use a partition manager to toggle boot flag

But if a disk contains large files over 4096 megs, they wont work in fat32

For Mac Disks, Best to convert the disk to DMG, then use A. Win32diskimager in windows (Its basically dd) And just select the DMG (drop box "all files" first) and click "write"

It will add the EFI partition, and the HFS+ parition to the USB, and it will boot.

This has worked for all the disks I needed.
