Boot device question

[Walter Goldschmidt]

I replaced my internal hard drive in my computer and everything is fine
there. My problem is when I backed up my data from old hard drive I messed
up when backing up my saved email. Now I want to retrieve this information
from the old hard drive so I bought an external case and put old drive in
it. Now I can plug it into the USB port on my old computer and access it. I
thought I would be able to boot my old computer from the USB port but it
only allows me to boot from A\, C\, or the D\ (CD Drive). Not the USB port.
On a newer computer I would have been able to boot from the USB port but
when I tried it said there was different hardware detected and it would not
allow my new computer to boot from the old drive. Is there any way for me to
get my old email messages from my old drive.
