Recouver MBR

Hi,

I have the following Problem:

I installed windows 7 then vista then Ubuntu. I had grub as primary boot-loader which chain-loaded the windows 7 boot-loader. Now I tried to install Linux Mint which overwrote the Windows 7 boot-loader. I tried to recover it but it didn't work (I tried bootrec and bootsec) because of the recovery attempt grub also doesn't boot any longer.

the Hard drive is partitioned as follows:
D:, dev/sdc1 System Reserved, 105MB, HPFS/NTFS, bootable
F:, dev/sdc2 Windows 7, 524 GB, HPFS/NTFS
G:, dev/sdc3 Vista, 105 GB, HPFS/NTFS
dev/sdc4 extended Partition (0x05), 105 GB containing:
-dev/sdc5 Linux swap, 4,1 GB
-dev/sdc6 Linux, 101 GB, ext4,
-dev/sdc7 Linux, 164 GB, ext4,
-some free space

bootrec finds my two Windows Partitions F and G but when i try to run Fixboot it fails saying "element not found"

What can i do to recover my partitions?

Can i somehow make a totally new Boatloader and MBR if so how?

*title should be recover sry for my bad english I'm not a native speaker.

I ran Startup Repair 3 times it says:
Root cause found:
The partition table does not have a valid System Partition
Repair action: partition table repair
Result: Completed successfully

But still nothing happens after boot.

Did you mark Win7 partition Active first before running up to 3 Startup Repairs with reboots between each?

You may need to wipe GRUB off the HD entirely as it can corrupt Win7 boot beyond repair, and may already have.

Finally some progress:
I unplugged all other hard drives and started the PC. I finally got an error message from the boot-loader instead of Grub starting up.
Message:

Code:

File: \Boot\BCD
Status: 0xc000000f
An Error occurred while attempting to read the boot configuration data

After that the System Recovery was finally searching for startup options instead of showing me no operating system to fix. I got the message:

Windows found problems with your computer's startup options.
Do you want to apply repairs and restart your computer?

under "view details" it showed me my lost windows vista and 7.

I restarted and BAM! My windows is back!


So what did I learn: Before doing all kind of stupid repair attempts with bootrec, bootsec, bcdedit, copying bootmgr to my operating system partition and what not just try following directions and UNPLUGG YOUR F***ING OTHER HARDDRIVES.

Now i should be able to reconfigurer grub as startup manager and everything is good.
