Need to edit registry on alternate hard disk 1

[PsalmBlaster]

Hi,
I recently edited my registry, removed a few keys that were in a tech guide (only to do with CD drives, mine had gone missing)

Anyway, after a restart I find my mouse and keyboard are nonresponsive. Removing and reinserting USB mouse leads to it being detected by windows but still no response frommovement. Also tried PS/2 keyboards and nothing will work. I made a backup of the changes I made to the registry, but even in safe-mode I cannot interact with the PC.

As a last resort I have grafted my XP boot disk onto a friends computer and can now access the files, I was hoping to be able to manually edit the files in windows/system32/config manually with the information stored in my .reg backup file.

To my dismay all the files in that folder are huge and not readable (coherently) in notepad, and I don't want to risk typing anythingin and making it worse.

Is there a way for me to get regedit to look at another registry, i.e. not the one that is being used on the computers running hard disk?

I have tried 'last good config' but no joy, also tried using a boot CD to get to the recovery console, that BSODs and I even wrote 6 boot diskettes with an MS app but they give me an error and wont take me to the recovery console (if that would even help)

Input works on BIOS and stops as soon as Windows gets involved at all.

I'm going on the assumption that it was my registry that causes the mouse and keyboard to not respond - if anyone has other ideas I'm open to them, but I doubt it was a coincidence.

If your drive is in its own machine, try System Restore from Safe Mode. You may need to navigate via the Keyboard.

"Windows keyboard shortcuts overview" (From Help and Support program).

Amending your registry on another machine by loading a Hive.

As an Administrator highlight one of the two following Keys, it will only be available for these Keys.

HKEY_LOCAL_MACHINE
HKEY_USERS

Thes two articles in the RegEdit Help are a good explanation of the process.

To load a hive into the registry
To unload a hive from the registry

Thanks for the links, I'll check them out.

I turned System Restore off and even in Safe Mode everything is dead Disk is still in friends computer to save me taking any more skin from my knuckles I only switch internals if I really have to

 

[PsalmBlaster]

Great time to notice I only backed up one subkey..

Anyone fancy making their [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}] information available to me do they?

Also it's cousin in "CurrentControlSet" (if that matters)

I can't seem to get Registry Mechanic or other similar apps to scan registrys that aren't the currently-in-use registry. Strange considering most of the Registry problems I've ever encountered made the computer magically turn into a paperweight.

Is there a Registry editor out there that allows me to copy and paste keys and values? I'm thinking I just merge my friends version of the files that are more-or-less the waymine were and just see if I can work it from there? Hand writing it will take hours and He gets home soon.

(I can't see an edit button so sorry for posts)

I copied my friends values into my registry but it still just sits on the desktop with no response from mouse or keyboard while google sidebar and other programs happily go on their way.

Keyboard won't light up Caps Lock light and USB mouse lights up but doesn't do anything when moved. After a while power saving cuts in, monitor gets turned off and mouse or keyboard movement doesn't bring it back to life.

Housecall isn't finding any infection so far on the disk, I still don't know if it is the registry, a virus or something else. Founda similar report on another forum, theirs was a virus so fingers crossed for the last part of this scan (never hoped to see a virus so much!)

 

[linney]

Save any file (to Disk if need be) that you want to add to your Registry as a .reg file and use the import function in Reg Edit to merge the file into your Registry. You can also right-click on any .reg file and select Merge. BE CAREFUL!

No joy..

I see a lot of this kind of problem in Google groups from a few years ago but no fixes (somone suggested replacing registry from repair folder but thats years old for me)

MS Knowledge Base doesn't seem to have anything that exactly refers to me. I didn't alter any drivers prior to this happening and most of the MS articles are related to installing new Logitech drivers (my keyboard and mouse both happen to be Microsoft)

I've removed the 2 intellipoint items in my Registry's Run section, just incase it's the intellipoint software that's buggered - I haven't tested this just yet though.

I always seem to get hit by obscure problems, thisis nearly sa infuruating as the infinite loop graphics card problem

 

[linney]

Have tried uninstalling and removing devices in the Device Manager, rebooting, and letting Windows rediscover them? That might fix up any missing register entries for devices?

Any fix using the "replacing registry from repair folder" relies on having a Snapshot in System Restore so you can bring things up to date, otherwise you end up with a situation equal to the last System State backup, which may be equal to day 1 of the XP install. You could check the Repair folder and see how old the files are.

Starting to look like the only other alternative is a clean install, unless you have some other backups to fall back on?

 

[PsalmBlaster]

The repair folder does appear to be my fresh install before Uni started.. several years old :\

If I only use my system hive from back then will it still know where all my programs are and I only have to reinstall drivers etc? It's worth a try I think because it's still a little bit more convenient than starting from scratch.

Thanks for the help

 

[PsalmBlaster]

That seemed to work ok, a few minor programs needed to be repaired from their install programs but because my software hive was intact almost everything works fine after the drivers were reinstalled.

Handily because my files were all fine the drivers were still on my computer and easily findable.

Thanks for the help everyone

Here's a star for you linney!


Good advice + great people = tek-tips

 

[PsalmBlaster]

Any chance the topic of this thread could be changed to something a bit more relative to the problem? Like Mouse and Keyboard non-functional..

It might save anyone else having the same problem going through all the stages.

A quick rundown:

First I took my boot disk and put it into a friends computer
Then I just made a copy of my windows/system32/config folder (just in case)

Then I used the files stored in the windows/repair folder to overwrite the windows/system32/config files ONE-BY-ONE.

I suspected that the problem was with the system hive file not the software etc hives, so I started with that one, reverting it back to how the System Hive looks upon windows install. This caused minimal system upsets because the actual drivers were still on my system and the software hive wasn't fiddled with so apps still work fine.

I'm still not 100% on what caused the problem
