BOOTMGR missing after power outage. SPECIAL CASE!

[peterm1981]

Hi everyone, I know there is a million and one tutorials, fixes and guides online and youtube and trust me I`ve scoured all of them in the last 3 days. With no avail.
My problem is the following.
I had a power cut and my windows 7 didn`t boot after, total lack of boot record and boot partition.
I tried fixing with Windows 7 USB, repair it ways that it cant be fixed automatically and that I should contact microsoft. First of all in the repair usb, the operating system or drive is not shown in the window where it is supposed to show up.
I made an Aomei partition assistant boot USB and I saw that my system partition is OK, all my data is there. I set it to active, rebuild MBR and restart. Still nothing.
Went back to windows repair USB, command line. Used Diskpart to select disk, select partition, active, exit.
Used Bootrec /fixboot, success. bootrec /fixmbr, success. bootrec /scanos, success, found windows on C:
then i got to bootrec /rebuildmbr and says the system is not available or invalid.

For now I split the partitions and managed to use a 70 GB partition to install windows 7 to at least copy my files from the unbootable partition and my other SSD.

My question is.....why cant i copy or port the new install bootmgr or boot files to the NON-working old partition and make it active and boot again.
Nothing seems to work, I would need files from that windows OS for my work. Is there any way to ghost just the partition or something. So now my C is the new 70 GB partition with working windows 7 but I would need the windows on the old partition to also be bootable.

Appreciate all the help I can get....exhausted and stumped after 2 days of trial and error.

Do you have any shadow copies or a backup image?

If not, you can try this:Cannot get into Windows desktop. Stuck on black screen, DWM.exe crash

No I dont have shadow copy or image file. I only have a Windows 7 Installer.

If that w7 installer is the dvd for that computer, a repair install might work, it might ask for product key, hope you have it.

Did you try replacing the hives with backups - as explained in the link in my last post? Everything you need to do it is at that link.

Even if you have no shadow copies (and therefore no restore points), you have probably got hive backups.

No I dont have shadow copy or image file. I only have a Windows 7 Installer.

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 Command Prompt, type below command as shown and then press Enter:

C:

At the Command Prompt, type below 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 commands 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.

Try rebuilding the BCD again by executing the following, followed by Enter:

bootrec /scanos
bootrec /rebuildbcd

Restart your computer after rebuilding the BCD store.
