how can I manually build usb multiboot drive without multiboot manager like yumi

Question

I want to make a multiboot usb drive, but I can't find a good manager to do so. I have tried MultiSystem and yumi. MultiSystem does weird things with some of the isos, and makes a mess out of GRUB. Yumi didn't support most of the isos I gave it.

So my idea was to manual point a boot loader installed to the flashdrive at an iso file, also on the flashdrive. preferably the bootloader would be plop, or plopKexec, and would auto detect isos in a specific folder on the drive. but it would be ok to have to modify a config file whenever I add to the drive.

Will this work? if so, how?

Solution

Pendrivelinux.com has instructions for building a grub2 Multiboot from scratch:

I prefer the script from MultiBootUSB, again this uses grub2:
