@jmeyer said in How to Use FOG to PXE Boot MultiBoot 2k10 Unofficial:

chain memdisk iso raw

Just adding a bit of a caveat here.

memdisk is a BIOS boot loader only. There is currently not an equivalent function for UEFI based systems.

The iso image you boot from must be less than 2GB in size (remember 32bit address space) AND the booting computer must have at least 2 times the memory of the 2GB iso to function. So in the case of a 2GB ISO image, your computer needs to have 4GB of RAM.
