I want to run BT4 on my Gateway LT21. My Bios doesn't support booting from an sd card, but i want to run BT from a portable medium.
Since the LT21 has no optical drive, I cant use a persistent cd, and I don't want to have a usb drive sticking out waiting to get snapped off.
I would like to install BT4 on an sd card, and use a usb drive to boot the os, leaving me free to remove my usb drive, and run the os from my sd card.
i would assume that there would be some way to write the boot script to the USB without loading the entire OS on USB. Then re-write the boot script to direct it to the filesystem on the SD card.
The usb drive would be acting as a key as it were, being the only way to boot BT4.
