--- Comment #3 from Theodore Tso (tytso@mit.edu) ---
Free advice?   Before you do anything else, back up *everything* before you
even breathe on the system.  You may think it's not going to reproduce agai=
n,
but if it does, you may end up losing more data.

I tend to keep things very simple.  Which is to say, I try not dual-boot
Windows and Linux, and if I do, I use separate HDD's for the Windows and Li=
nux
systems.   So if I were doing anything like this at all, I'd boot into a Li=
nux
system, and then copy everything from the Windows partition to the Linux
partition in a single go, and then be done with it.   The KISS (Keep things
simple, stupid) principle is always a good way to follow especially with
valuable data.

And we're only talking about a 500GB HDD.  Getting a second 500GB disk, or =
for
that matter, an external 1TB HDD or even SSD, is cheap, compared to the val=
ue
of your time.

Backups.  Backups.   Backups.   I've worked at MIT, and seen a graduate stu=
dent
lose ten years worth of their research data due to lack of backups.   One c=
ould
perhaps claim that someone who was dumb enough not to make backups doesn't
deserve to have a Ph.D., but regardless, it's still a tragedy; and totally
avoidable.
