Windows broke my computer

Hi, most likely will have to reinstall windows.

Didi you try to boot with install disk and do a startup repair ?

Not every crash is the same. Describe what happens when "it always crashes on start up"

When you choose start up repair, do you get to a screen where you can choose to open a command prompt?

May wanto do a full HD check up when this thing finally boots.

Never trusted Windows repair, maybe the occasional directory inconsistency and that's about it. I always trust my external backup os image and boot with a recovery Flash.

Ok, at the command prompt, let's try these 3 commands:

bootrec /fixboot

bootrec /fixmbr

bootrec /rebuildbcd

You should see one of the following messages at the command line.

Option 1
Scanning all disks for Windows installations.
Please wait, since this may take a while...
Successfully scanned Windows installations.
Total identified Windows installations: 0
The operation completed successfully.

Option 2
Scanning all disks for Windows installations.
Please wait, since this may take a while...
Successfully scanned Windows installations.
Total identified Windows installations: 1
[1] D:\Windows
Add installation to boot list? Yes<Y>/No<N>/All<A>:

If you see:

Option 1: Move on to Step 5. This result most likely means that Windows installation data in the BCD store exists but bootrec couldn't find any additional installations of Windows on your computer to add to the BCD. That's fine, you'll just need to take a few extra steps to rebuild the BCD.

Option 2: Enter Y or Yes to the Add installation to boot list? question, after which you should see a The operation completed successfully message, followed by a blinking cursor at the prompt.

5. Since the BCD store exists and lists a Windows installation, you'll first have to "remove" it manually and then try to rebuild it again.

At the prompt, execute the bcdedit command as shown and then press Enter:
bcdedit /export c:\bcdbackup
The bcdedit command is used here to export the BCD store as a file: bcdbackup. There's no need to specify a file extension.

The command should return the following on screen:
The operation completed successfully.
meaning the BCD export worked as expected.

At this point, you need to adjust several file attributes for the BCD store so you can manipulate it.

At the prompt, execute the attrib command exactly like this:
attrib c:\boot\bcd -h -r -s
What you just did with the attrib command was remove the hidden, read-only, and system attributes from the file bcd. Those attributes restricted the actions you could take on the file. Now that they're gone, you can manipulate the file more freely - specifically, rename it.

To rename the BCD store, execute the ren command as shown:
ren c:\boot\bcd bcd.old
Now that the BCD store is renamed, you should now be able to successfully rebuild it, as you tried to do in Step 3.

Note: You could delete the BCD file entirely since you're about to create a new one. However, renaming the existing BCD accomplishes the same thing since it's now unavailable to Windows, plus provides you yet another layer of backup, in addition to the export you did in Step 5, if you decide to undo your actions.

Try rebuilding the BCD again by executing the following, followed by Enter:
bootrec /rebuildbcd
which should produce this in the Command Prompt window:
Scanning all disks for Windows installations. Please wait, since this may take a while... Successfully scanned Windows installations. Total identified Windows installations: 1 [1] D:\Windows Add installation to boot list? Yes<Y>/No<N>/All<A>:
meaning that the BCD store rebuild is progressing as expected.

At the Add installation to boot list? question, type Enter Y or Yes, followed by the Enter key.

You should see this on screen:
The operation completed successfully.
meaning that the BCD rebuild is complete.

10. Restart your computer.

Assuming that an issue with the BCD store was the only problem, Windows should start as expected.

I should have edited that - the options are more like possibilities. You'll get 1 or the other. If you get option 1, then proceed with the steps starting at 5.
If you get option 2, select yes and restart the computer.

Skip down to where you it says:

Preparing Windows 7 Recovery

And try following that.

Starting Windows normally does nothing now?

You will see that anytime you have this or similar problems.

As for using the Windows disc for the startup repair, it won't work any better than what you tried before.

Were any of the files in the regback folder size 0?

Then that repair won't work. It says that in the directions.
