System Recovery can't find my c drive

OS: Windows 7 Enterprise 64 bit

Dear all,

I was playing with a linux pen and accidentally overwrote the MBR. Usually this is easy to fix, but not this time.

As I have a bootable pen with windows, I started the computer with it and used the normal procedure to fix the boot issue using the command prompt (bootrec /rebuildbcd and bootrec /fixboot).

A very important detail is that I have used a 32 bit Windows (in my pen) trying to recover a 64 bit system.

I thought it could work since I only had to restore the MBR, and from my understanding this is the same regardless the windows version.

The main problem, now, is that when going to the command prompt drive c no longer exist.

Doing c: doesn't work, using diskpart doesn't work.

Any ideas of what I can do ?

Thanks in advance.
Best regards

When you say c doesn't exists could it have another drive letter if you boot a live Windows the CD may be c as it's booting from it can you see a partition for c? Are you sure the disk is MBR not gpt or uefi?

Hi,
When I said MBR I wasn't accurate att all, I meant a problem in the partition table that prevents booting (I think it is UEFI on my case).

I am using a live windows 7 pen to rescue/fix the system. When the windows starts, it shows up an option to go to a prompt window. The first 2 or 3 times that I used this pen, I could access the drive C (typing C: ) but now it doesn't recognize C partition. It is not found. As I said previously, diskpart can't find any partition neither. So it is as the ssd had disappeared.

Legacy-MBR boot is completely different from UEFI-GPT.
Fist of all, you must find out witch one you have. Boot Linux and find out if your disk is MBR or GPT and if there is a 100M Fat32 partition.

According to Linux is MBR. Running a program called gdisk the following is returned:
"Found Invalid GPT and valid MBR" Main Partition Table overlaps fist partition by 33 bytes.

Doing fdisk, only a partition appears with 62.8 MB. The remaining 465GB appear as empty (partition does not exist) although having information.
Can I create a partition where the data is so I can see the data again ? Does that make sense ?

Don't try to fix it.
Is your disk a HDD or SSD? Is it a 500G?
What exactly did you do on fist place.

Do you have another computer where you can plug the disk and use some tools to repair it?

Hi,
The disk is an SSD and I've tried to fix the boot using a 32 bit Windows bootable pen, but my OS is 64bit.

I used the normal instructions that you can find on the net:
bootrec.exe /fixmbr
bootrec.exe /fixboot
bootrec.exe /rebuildbcd

How to Fix Windows 7 When It Fails to Boot

Now the error when turning the computer on is:

File: \Boot\BCD

Status: 0xc000000f

I can't rebuild BCD using the bootable pen because it doesn't find any partition. So, all of the commands below don't work:

bcdedit /export C:\BCD_Backup
c:
cd boot
attrib bcd -s -h -r
ren c:\boot\bcd bcd.old
bootrec /RebuildBcd

Hi,
Thanks a lot for the files.
I have chosen "fast search"and it is still at 0% after 20 minutes, is this normal ?
Thanks,
Pedro
