    That just gave me a thought, which I haven't looked at don't think me it possible to boot off an SD card in a tablet....format it, load the OS and using partition magic or computer management, change the embedded C: to D: and thus D: to C: and have the tablet boot? I doubt it....but does anyone know if that could possibly work...or is the boot drive always fixed in a tablet?

    Most SD Cards are not bootable
    And too slow for the OS to run from. BUT.... this is interesting. Most of the time there is a partition (usually 100mb to 500mb in size) that is "reserved" for the boot files. Then there is the partition for the operating system. Most SD Cards in computers/tablets require operating system drivers in order to be recognized so even if you copy the OS to the SD Card, it probably could not be run from the SD Card because it would not be recognized until the OS loaded.

    BUT, if you wanted to try. Copy the OS partition only to the SD Card. Do not copy the system reserved partition. Then add a second boot entry to the BCD store located on the small reserved partition pointing to the OS copied to the SD Card. (I would recommend EasyBCD for that). Basically, you will have dual boot setup with first option to the OS on the "hard drive" of the tablet, and second option to the OS on the SD Card.

    Right. Never given a choice to inssall the OS to it. But certainly great for the purpose of storage as required.

    The BCD option is intriguing. Since this is just an experiment with tablet, no harm in trying something new for the heck of it...thanks
