    So I followed this guide: http://www.elinux.org/UDOO_boot_from_sata

    And successfully have debian wheezy booting from my SSD. Problem is, I'd like to actually use this sd card and possibly future larger ones for storage space while still making it bootable.

    On the final step that says Done! it says "If all goes well you can safely remove almost everything on the SD card."

    However, it doesn't specify what! I'm guessing what needs to be kept is the kernel and uboot. So could anyone tell me exactly what files I need to keep so that it's bootable?

    Extra off topic question:
    Does it inevitably run 24/7 upon being plugged in, like is getting a power and reset switch pointless? Fan i have hooked up still spins when it's "off"

    The only thing needed on the SD card is the u-boot. That is stored in the first sectors, before the partitions, IIRC. So you can remove everything on the SD but the actual file system. The kernel can be loaded from SATA.

    Oh, i didn't know it was just a sector. Thanks! That should probably be stated in the wiki page.
