I typed in bcdedit | find "osdevice" but nothing happened

I assume I should put a space between bcdedit | find and "osdevice" just as you have?

Hi Apollo18

I would like to try out the following to see if this will help. Ensure you are at the command prompt X :\Sources>


1. At the prompt, type the bootrec command as shown below and then press Enter:

bootrec /rebuildbcd

The bootrec command will search for Windows installations not included in the Boot Configuration Data and then ask you if you'd like to add one or more to it.

2. 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>:


3. If you see:

Option 1: Move on to Step 4. 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. Finish up with Step 7 toward the bottom of the page.


4.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.


5. 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.

6. 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.

7. Close down the command prompt and remove the USB drive then Restart your computer. Press F2 to enter the bios and amend the boot priority back to internal hard disk drive and disable external device boot. Save and exit.

Let me know if the computer boots normally.

Thanks Bruce. I got the Option 1 message but I have come to a problem in step 4.

I typed in bcdedit /export c:\bcdbackup but got the following message:

 

The store export operation has failed.

The volume for a file has been externally altered so that the opened file is no longer valid.

Hi Apollo18

Ok try this bit first.

At the command prompt type DiskPart and then press return.

The prompt should change to DISKPART>

At the diskpart prompt type list volume and press return.

Copy and paste the information into notepad and paste into your next reply.

Hi Apollo18

I'm afraid I have very bad news :(

Your disk is being recognised by the BIOS but there does not appear to be anything on it. Not even the recovery partition drive.
 

DISKPART> list volume

Volume ### Ltr Label Fs Type Size Status Info
---------- --- ----------- ----- ---------- ------- --------- --------
Volume 0 D DVD-ROM 0 B No Media
Volume 1 C 2007_11_03_ NTFS Removable 504 MB Healthy


Unfortunately this means it cannot be recovered and your data is lost. Do you have a back up or image of your system?

Your option is to reinstall the system - as you do not have a installation disc you might be able to contact the OEM manufacturer and see if you can order recovery disks for your operating system. I think there may be a small charge for this. On the bottom of your computer you might find a sticker with the product key, you may need this when ordering.

Alternatively have a look at this microsoft page for additonal information and help.

Or as Vista is an older operating system it might be time to consider upgrading to the latest Windows 10. Unfortunately Vista does not offer a free upgrade to windows 10 similar to windows 7 or 8/8.1.

Once you are back up and running I would recommend the following -

Create a start up repair disk or USB - How to create a startup repair disk

Regularly image your system using a imaging tool such as Macrium Reflect. A tutorial on how to use this can be found here. That way you have an image you can restore to if the worst happens.

I am very sorry we could not get a better outcome.
