Hi friends!

I have two operating systems(Windows XP SP3 and Window Vista) on my
computer, I would change some parts of a file content named “advapi32.dll”
which is located in “/Windows/System32/” directory of Windows XP SP3.
So, I run Windows Vista and changed this dll’s content through a software
called “HxD”(Hex Editor).
But unfortunately, I forgot to take a backup of it and changed it
inappropriately!!
Now, my Windows XP isn’t loaded!
I want to repair my Windows XP through “Recovery Console” and retrieve this
dll file from Window XP’s CD to fix this problem;
But, I don’t know which command of “Recovery Console” should use to solve
this case!

Could you help me about this?!
I really don’t have enough time to reinstalling XP!!!

One another question!
How can I change a file’s content (for example, this “advapi32.dll”) in
Recovery Console? (i.e. with which command?)
I want to see it’s contents in Recovery Console and can change the values
present in some Offsets!
Please help me!!!

Thanks in Advance.

Use the Expand command to replace the .dll you screwed up.
You can not edit files using Recovery Console but you can view .txt
files [MORE or TYPE] and run .bat files [BATCH].

You've already made the system unbootable once ... are you sure you want
to do it again ? If yes, then use the same software but *back up* the
file first.
