Solved How to make Windows 7 get working again (black screen with a cursor)?

[g1o2r3a4z5d6]

So, the story started with permissions I changed in the registry and by adding 'Everyone' to the key, it simply deleted every user instead and also the owner. The computer hasn't booted until then (black screen with a cursor). I used WINDOWS 7 Recovery CD to repair it.

I've been successful in applying permissions back, thanks to this post: Fix Permissions Changes Preventing Windows From Booting (Windows 7 / Vista) - Sysnative Forums

But now my system still won't boot. I get black screen with movable mouse cursor. Safe mode, last known good configuration and system restore all don't work. I tried almost every combination in diskpart, however, still no luck. Here's the info for the one who is more experienced than I am and would be kind enough to help me.

Diskpart shows 1 disk, when I select it, it is divided into three partitions.

The first one is: Volume 1, Letter C, Label=system, fs=ntfs, primary partition, 500 MB and healthy
The second one is: Volume 3, Letter E, Label=recovery, fs=ntfs, recovery partition, 6000 MB, healthy and hidden
The third one is: Volume 2, Letter D, Label=OS, fs=ntfs, primary partition, 925 GB, healthy

According to this tutorial How To Rebuild the BCD in Windows I had been able to get 'Total identified Windows installations =(1)' if I chose D. So I assume Windows is installed on D:. I may be wrong. When the computer worked, I did not see any D: disk in My Computer (only C: with OS).

The problem is, I cannot choose which of the following partitions I should make active so the black screen wouldn't appear.

When I enter in cmd:

vol C: -> Volume in drive C is system
vol D: -> Volume in drive D is OS
vol E: -> Could not find the following drive. Error while processing. Volume in drive E is recovery.
vol X: -> Could not find the following drive. Error while processing. Volume in drive X is boot.
vol F: -> Could not find the following drive. Error while processing. Volume in drive F is GRMCHPXFREO_EN_DVD

When I enter in cmd:

dir C: -> Volume in drive C: is system
dir D: -> Volume in drive D: is OS. (Followed by all my personal data and folders)
dir E: -> Volume in drive E: is Recovery. Only Recovery folder (from 2011)
dir F: -> Volume in drive F: is GRMCHPXFREO_EN_DVD. (I assume this is the Recovery CD)
dir X: -> Volume in drive X: is boot. (Followed by many .dll files and .xsl files)

I am a bit confused as some letters are quite different from the ones that were listed when my computer was working (There was only C: drive in My Computer, CD was drive E:, not F: as above...) That's a bit confusing for sure.

I want someone to tell me: Which PARTITION I should make active and where I should configure boot. I gave it up as it's apparently too complicated for me but I need the files stored on the computer as well as the programs. So please, don't tell me to do a repair or custom install.

Also someone should tell me:

On which drive (or volume) I should run this command: net user Administrator /active:yes ?

Which partition to make active?

On which drive (or volume) I need to run: bootrec /fixmbr, bootrec /scanos, bootrec /fixboot, bootsect /nt60 all (is this link any useful: How to Manually Repair Windows 7 Boot Loader Problems ?)

I also tried this: http://www.sevenforums.com/tutorials/105541-startup-repair-run-3-separate-times.html

Does this refer to my problem? http://www.sevenforums.com/tutorials/139810-sfc-scannow-run-command-prompt-boot.html

I tried to compare my settings with my mothers' laptop which is working (both Windows 7 SP1 64 bit) but the settings are still so different that it isn't of any help.

Please, are here any heroes?

Thank you so much in advance.

If there's any more info I should have mentioned or anything, please request and I'll provide it.

I hope someone here will sacrifice their time and help me. I need the files so desparatley.

You state; "But now my system still won't boot. I get black screen with movable mouse cursor. Safe mode, last known good configuration and system restore all don't work. I tried almost every combination in diskpart, however, still no luck."

How are you accessing DiskPart?

 

[g1o2r3a4z5d6]

I used WINDOWS 7 Recovery CD to repair it.

Thank you for the answer, Sir George.

I use my installation disk (Windows 7 64bit Home Premium) and from there through System Recovery Options there is an option Command Prompt.

Use a different computer and create a WinPE disk using the following link as a "how to" guide:

Create a Bootable Windows PE Disk - Spiceworks

Post back afterwards.

 

[g1o2r3a4z5d6]

Thank you for the suggestion. I'm running grant permissions on C: drive, then will try to boot again and if I'm unsuccessful I'll try your advice. I will inform you.

It seems you ruined your install through utterly reckless tampering with the registry.

I would follow the same steps for a Clean Reinstall - Factory OEM Windows 7 to get and keep a perfect install, then stick with only the tools and methods given which have worked best for tens of thousands we've helped here.

I doubt this will work but here it is none the less,

I tried to change the registry values (via cmd on Recovery CD).

HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\Winlogon

shell was: cmd.exe /k start cmd.exe
userinit was: X:\windows\system32\userinit.exe,

But if I change it back to explorer.exe and replace X with C then restart, still get black screen.
Then go back to look at Recovery CD and type regedit in cmd and seems like registry didn't save my corrections.

What to do now?

 

[gregrocker]

I told you what to do, quite specifically. Any questions?

 

[g1o2r3a4z5d6]

Yes, I want to know why regedit won't save my changes.

 

[g1o2r3a4z5d6]

@Gregrocker And I told you quite frankly that I'm not going to reinstall Windows.

You don't know what you're doing!! You were booted form recovery CD to some mini win7. The commands affected the mini win7 (in ramdisk, so destroyed anyway later). You have to change the rela win7 on partition labeled OS.

Problems began after changing the registry permissions? That was all you did initially?

 

[Kaktussoft]

Yes, I want to know why regedit won't save my changes.

Because you change the registry of winpe (mini win7 for recovery).

 

[g1o2r3a4z5d6]

Kaktussoft, yes exactly that was the main problem. It deleted owner and all premissions in the branch ROOT in the registry.

I thought that it was the registry of the Repair CD. Do you know what to do to repair the registry on computer via cmd on recovery CD? If I click load hive in Recovery CD I can see all my files and partitions as followed:

System (C -> only Temp folder in it
OS (D -> Actually the content of the whole computer
Recovery (E -> Recovery folder with nothing special in it
Boot (X -> The content of the recovery CD

 

[Kaktussoft]

Why did you think the bootmenu (BCD) was faulty... it DID start and does still start win7!
Why messing around with partitions?
Why did you reset file permissions to default? They were not wrong... =>resetting to default doesn't hurt.

 

[g1o2r3a4z5d6]

Because on the other forum they told me it's the problem. And Windows 7 on my PC doesn't start.
Because I wanted to get my Windows 7 working back as it was perviously.
They were wrong because I changed them by mistake.

 

[Kaktussoft]

In recovery environment select "system restore". Go back in time prior to date/time when problems started.
http://www.sevenforums.com/tutorials/700-system-restore.html

All exe, dll, registry and other windows files will be rolled back to that time. Data files like WORD and excel documents are untouched.

 

[Kaktussoft]

In first post you say: "Safe mode, last known good configuration and system restore all don't work."
What error message when doing "system restore"? Restore points are listed?

 

[g1o2r3a4z5d6]

The error is: No restore points have been created on your computer's system disk.
But I didn't delete any of them and I remeber they were there the same day!

If it was that simple, I would already do it.
