I have an XP machine. Have just replaced a couple files from a W7 machine.

The files are:-

c:\windows\system32\drivers\disk.sys

c:\windows\system32\drivers\partmgr.sys

....and now I can't boot the XP machine.

How to get back to before I replaced the files?

Thanks.

Boot the machine with a Bart PE boot CD (or equivalent), then replace the

files from your WinXP installation CD. Alternatively you could connect the

disk as a slave disk to some other WinXP PC, then replace the files.

System Restore is usually the simplest day to

reboot WinXP in a known good configuration.

======================

How can I do system restore?...I don't have a system restore CD. I have the

original XP CD if any good - but would like to not have to zap everything by

reinstalling Windows.

Thanks.

There is no garantee this would work and it might have undesirable

consequences, depending on my the OP did on his machine before the

problem became evident.



Both files are located in c:\I386 with a sy_ extension. Expand each file

by using the expand.exe command located in c:\i386.

boot up the XP CD. It is years since I last did it but you will be

offered very options. Consider them carefully. Restoring the missing

files the way I suggest is certainly the least potentially risky option.

Why would you put Windows 7 files on an XP system?



If all you did was overwrite two files, there are copies of the

original XP files in other places on your XP system that you can copy

back to where the original ones belong. It is a simple matter to

replace the improper files with XP files.



You do not need to do a system restore, you do not need to make a Bart

PE CD, you do not have to move the drive to another system, etc. You

can't make a Bart PE CD without an original XP installation CD anyway

- it is a requirement to even start, and then, what would you do next

even if you had a Bart PE CD? If you were able to move the drive to

another system as a slave drive, what would you do next?



You can replace the two files easily from the XP Recovery Console.

You can boot RC using your original XP installation CD, or you can

make a new bootable Recovery Console CD (which may come in handy some

other day). Many folks do not have original bootable XP installation

media, but that is no issue if all you need to do is replace two

files. Just make a bootable RC disk, replace the files and be on your

way.



You can create a bootable XP Recovery Console CD when no XP media is

available:

When you afflicted system booted into the recovery console, let us

know and we will give you instructions on how to replace your two

files.

Sheesh! He would do what you expect him to do in the Recovery Console

but he would do it in a GUI environment rather than at a command line

and he would have way more options available to him than the handful of

commands available in the Recovery Console!

Read about it here:



http://www.nu2.nu/pebuilder/

Bart's Preinstalled Environment (BartPE) bootable live windows CD/DVD



Making a PE Disk can be a bit of a daunting task for a novice, if you

want you can download a "pre-made" PE disk here:



http://www.ubcd4win.com/

Welcome to the UBCD4Win.com



Even though you can download a pre-made disk you still have to build the

CD and you still need a Windows XP CD to build it. Read the FAQ.

If the OP doesn't know how to replace two system files what do you

think the chances are of coming up with an original XP installation CD

that matches his installation, downloading, building and creating a

Bart PE (or equivalent) CD on a functioning system, testing it,

successfully booting the afflicted system using it, navigating some

probably never seen before GUI and successfully locating and copying

two files - and how long will that take.



Will someone volunteer to walk the OP through using a Bart PE CD to

replace those two files?



Or what do you think the chances are of removing the afflicted HDD,

configuring it as a slave drive, moving it to another computer and

replacing the files and putting it all back together again? How long

will that take? What if it is a laptop and the drive is not easily

moved?



I also don't understand how to implement a System Restore on a system

that will not boot either, but that would be a good trick too and do

you really think SR will magically replace those two mismatched files

with XP versions?



Once booting into RC, replacing the two files is generally just

entering 2 commands. If you can type, you can do it with a fraction

of the effort and time.



So far, most people are able to follow simple directions to make a

bootable RC CD and that eliminates the need for any original XP media,

puzzling over some new GUI, or moving any hardware around. Yes - by

all means compose instructions on how to create and build a Bart PE

and replace those two files. No link was provided to Bart PE either,

so I will need all those instructions too. Pretend I know nothing

about any (equivalent) environment and get me started.



But the chances are also pretty good that there is something else

going on besides simply replacing two mismatched files, that is the

easy part. There is no notice of what provoked this action in the

first place. After replacing the two files the system still may not

boot and then the original problem can be investigated.

The OP said in another post that he does have a real Windows XP CD and

the instructions on the UBCD4Win are fairly clear and straightforward.

I have noticed that you often like to take 'pot-shots' at suggestions

offered by others and that these pot-shots sublimely suggest that your

solutions are right and that the others aren't. By all means when

errors or incorrect and ridiculous advice is given you should point it

out, but just because the other suggestions differ from your preferred

solution it doesn't make these other suggestions wrong or incorrect.

The Recovery Console is one way that the OP can use to restore the file

but it isn't the only way, the suggestion to use a PE disk is just as

valid as yours... and discovering the usefulness of tools like the PE

disks is a valuable lesson for novices.

Thanks Jose...ref why did I do it:-



I know I know....!!

Reason was I have an external hard drive that works ok on the W7 machine but

not on the XP.

When looking at Device Manager in W7 it showed that the two files mentioned

were shown as drivers

for the EHD...whereas on the XP machine, although Device Manager doesn't

show a problem, the drivers shown are pretty old...2001..

...hence decided to copy them to the XP machine...WRONG!...



....and now I've used the original XP CD, clicked on R, Recovery Console,

loads of files loaded and I'm now at the C:\> prompt

...instructions as to how to replace back the two files now would be

appreciated.

It's just a straight copy command, e.g.



copy e:\i386\disk.sys c:\windows\system32\drivers\disk.sys



Whether the Recovery Console lets you write something into the Drivers

folder is another question. Many folders remain out of reach while in RC

mode unless you tweak the registry while Windows is still up and running. If

so then you need to use of the methods I suggested in my initial reply.

I take it you haven't checked that site in a while...

Ultimate Boot CD 4 Windows (UBCD4WIN) used to have an .iso image but

now you are required to build it as well. I think it is a copyright

issue.

What worked and what solved you issue. In alt.24hr,helpdesk they told you something

completely different for the fix and you posted there that it worked and thanked

them. Here in the public.windowsxp newsgroup you did the same but for another fix.

So which one worked. I doubt what BD told you worked or anybody else there worked.

Help me out here and let us know

Given the various followup questions asked by the OP,

I suppose it would be way too much to expect him to

have a recent backup of his system, from which he could

selectively restore the two files in question.

Good.



When you boot into RC you should be in the C:\WINDOWS folder - not C:\

so hopefully there is not another problem or some typo somewhere in

your reply.



XP has copies of those files here:



c:\windows\system32\dllcache



You need to copy those two files to the target folder:



c:\windows\system32\drivers



From your RC prompt you would enter two commands:



copy c:\windows\system32\dllcache\disk.sys c:\windows\system32\drivers



copy c:\windows\system32\dllcache\partmgr.sys c:\windows

\system32\drivers



Respond in the affirmative (Yes) when asked to overwrite the existing

file and you will get a message that 1 file(s) was copied. Do that

for both files replacing them with the original XP versions.



I just tried it from my RC and it works fine.



Reboot and please report back your results or issues.

-------------------

Yes its c:\> I'm at not c:\windows

from the c prompt did copy c:\windows\system32\dllcache\disk.sys

c:\windows\system32\drivers

but got the note..the command is not recognised?

How do I change from c to c:\windows?

Could it be that c:\windows\system32\dllcache\disk.sys is niot the same path

as mine.?..how do I check that?

Yes, but it comes pre-assembled with various plug-ins. With the

downloaded file building the CD is somewhat similar to doing a

slipstream and is easier than assembling the whole thing from scratch.
