Windows 7: Win 7 cannot start, restore or repair possible damage to MBR

Win 7 cannot start, restore or repair possible damage to MBR

Hi,

I am running win 7 x64, I did create a recovery disk in 64 bit, and my laptop also came with a 32 bit recovery Disc.

Yesterday I found out I was infected with a tidserve virus, I used a removal tool from Symantec which seemed to fix the issue, before restarting I also removed some other anti virus software I had installed to try to remove the virus.

After rebooting, my laptop went straight to start windows normally or run repair, it cannot repair.

I have tried using the repair on the disk that will not work or finds no problems.
system restore will also not work.

I have just tried /scannow from command prompt and it tells me it cannot find any intgrity violations however I think I remeber the tool from symantec telling me that the file 'MBR' was infected and it fixed that.

I believe this is the source of my inability to now start up windows.

any help or advise is appreciated.

I am able to back up all my files using command prompt to external HDD but of course if this could be fixed without a complete reinstallation that would be great.

Many Thanks

Hi

Yes, tried that first thing this morning and it said it was successful. this is why I now wonder if MBR is really the problem at all and not merely a coincidence.
I am now running CHKDSK waiting to see if that tells me anything

Hi theog,

thank you I will try that as soon as chkdk is fiished.
I should add I am really not that great with pc's, My husband was the one who helped me repair the MBR using a method he found on here, but he is at work now leaving me to try to fix this issue.

Thanking you both for taking the time to assist me

So you put the oem re-installation disc and did a repair by select "R" at the second prompt (which is where the system detects an already install OS) and it still failed to repair?

I don't like your chances if the chkdsk /r also failed.

Get ready for a new install

Hi again, lol yeh first thing I did ! A lot of good its doing me at the moment however

I tried to follow your instructions.

I suceeded as far as :

bcdedit /export c:\bcdbackup
the operation completed successfully

X:\windows\system32>c:

c:\> cd boot

The system cannot find the path specified
