Bootable USBs

Hi,

What are you changing in/on a USB when you make it bootable?

Why must you make this change in order to boot an operating system from it?

Why are some operating systems easier to boot from a USB than others?

Apparently, Tails and Linux are readily USB bootable, but Windows may be more difficult.

Thanks.
 
He's posted the same thing to Anandtech and got some other answers.

I don't think the bootflag is BIOS dependent rather than the medium you are booting from. Like USB vs SD card. I don't even know if you can boot from SD card. Which would be slow as a snail.
 
You can boot from SD Card. They're just not the fastest.

It would still work on standard desktops, but just as a note, HP Proliant servers have SD cards in them you can use when you're using a bare server for VMware ESX. You install ESX to the SD card, and then once it's booted, it just runs in RAM.
