I agree all the way - I guess my real question is whether a DELL (or
for that matter a GATEWAY or COMPAQ) will boot up and start Windows
from another Hard Drive. In other words, would DELL have changed the
MOBO to only work with their modified OS?
No, Dell does not change the mobo and their "modified OS" is
pretty much normal except they add some customization that
has nothing to do with booting or adding a hard drive.
Whether the Dell will boot up from a hard drive with an OS
installed to it while it was in another computer, depends on
that OS, not on it being an OEM box like Dell, GW, Compaq.
YOu seem to be asking a generic question instead of
providing specifics, so a generic answer is all that can be
provided... you dont' mention the exact goal here, since
there are a dozen ways to get data from one drive to another
or make it accessible to the new box.
If the old box works, the easiest thing would be just
networking them, adding a nic to either as needed, then you
still have ability to comm. between them too.
