yup, I tried the m'soft tool, when it finishes with the flash drive it explicitly tells me that it did not make it bootable, and I tried resetting the boot order and everything on the other computer.
The info page about the tool also says that you can't make it bootable on a 32 bit version of windows if you're trying to put a 64 bit windows on the flash drive when you're using a 32 bit version of windows, which I unfortunately am in the position of doing =\. And the solution windows provided for it is something I can't do, to top it off.
