re: MBR problem in hard disk

Rewrite Master Boot Record (MBR)
  1. Download program Master Boot Record Auto write from this site : http://us1.download.acronis.com/supp...towrite_en.iso

  2. Burn disk image to CD.

  3. Boot your PC from this CD.

  4. After you boot your PC, you should find this message :

    Starting Acronis Loader?
    XFDisk http://home.pages.de/~xfdisk will rewrite your
    Master Boot Record [MBR] automatically.
    Remove data medium and reboot now if you don?t want this.

    Press any key to rewrite MBR?


  5. Enter and you find this message

    Starting Acronis Loader?

    Master Boot Record [MBR] automatically.
    Remove data medium and reboot now if you don?t want this.

re: MBR problem in hard disk

Looks like he MBR of your hard drive has got corrupted. Have you run any drive testing software on it? Usually there are free tools available at the website of the hard drive manufacturer.

Run the tools from the manufacturer and see what you come up with - could be that the drive is failing and will have to be replaced.

Do you have windows 7 disk with you because it will be helpful to take the option of repair from the disc in order to fix the corrupt MBR table, if it might be so. Other things you could do is, take the hard drive to your friends place and connect it in his computer and retrieve all the data and then freshly install the windows operating system from start onto the hard drive.

Re: MBR problem in hard disk

Thanks for reply..but i want to retrieve the data which is in ubuntu..is it possible..

My problem started when i i kept VISTA bootable cd..that vista cd was not proper..so installation of vista stopped beacuse of a corrupted or missing file..

Then Windows7 started getting startup repair problems ....
then i tried to repair it using windows7 cd....it was not done..

So i thought may be MBR problem so i did the following..
i typed the following in command prompt of startup repair

bootrec.exe/ FixMbr
Then message came as Operation successful.
Then i typed bootrec.exe/ FixBoot
bootrec.exe /RebuildBcd

THen it showed Operation Successful.

Then i typed
bcdedit /export c:\BCD_Backup
C:
cd boot
attrib bcd -s -h -r
ren c:\boot\bcd bcd.old
bootrec /ReBuild Bcd

Then i typed last 6 lines again..
then exited

When it was restarted it showing two Windows7 Ultimate options for me and keeps restarting....

Just tell me i can see all the data if i connect the hard disk to another PC
and be able to retrieve the data of ubuntu files...
