The system will not know what to boot.
When you boot off a flash drive it starts at the physical beginning or somewhere towards the front and reads instructions from there, and so THE BIOS DOES NOT KNOW HOW TO READ ANY FILE SYSTEM FORMAT.
The flash drive must have at least one instruction at the beginning to have the processor jump to a memory location in the kernel file to start running instructions from there. AT LEAST
So not writing those 4 bytes (32 bits)to the beginning to the flash drive is all it will take to keep it from booting. And those 4 bytes are not located in a file. They are represented in some way by the ISO at an absolute memory location on the flash drive. Which is why you use a CD burner, so it can write ALL the data onto the flash drive at specific locations in a specific order. |
