Ohhhk, so MBR is a hard drive format.. it comes standard with every windows unit.. Have you tried to plug this Hdd into a Mac unit?

If not we can go through a wipe process which will reset the Hdd into a MBR format, but your data will be lost..

Can you use this Hdd as an external unit to back your data up?

Ohhhk, soo..

To not loose your data you need to connect the Hdd that's in that faulty unit into a working computer.. not a super hard task...

This may help:

Then...

Once you have retrieved the data use this guide to reformat the Hdd into a MBR format:

Note: I cant view these youtube items, so I cant tell if there spot on to what you need to do.. but Im sure you will have a good idea..

Let us know how you went.

But the Error message is regarding my Laptop itself and not any external Hard
drive. I have everything on my Laptop. And my Windows Vista Operating System is on the Laptop and i have all my projects and Data on my Laptop.

So How to fix ---- Incorrect MBR without any loss of data. I am worried that I may lose my data.
Are there any Commands that I can execute at Coomand Prompt to fix
MBR?

Thanks

Yes.. lol you can... I know the command by heart... but once you "clean the disk" and reformat you WILL loose your data that's why its important to BACK YOUR DATA UP FIRST (if possible)... of another Pc.. and then repair/fix the Hdd.. and then retrieve data/load os back on..

The error is not Laptop related... MBR is a hard drive format... that is required for booting or reading externally as a device... there is a good chance you have already lost your data..

Is this HDD an external device or a internal Hdd (Thats inside the Laptop)

Unfortunately there is no magical commands that will format the Hard Drive without wiping all the data on it..

HDD is an Internal HDD that is inside the Laptop. I have my main Operating System (Windows Vista)
on it and I have a lot of data and my projects in the C Drive which is having my operating System

O.k. I 'll try to back up all the data. Then how to fix Incorrect MBR?
Are there any commands that can be executed at the command Prompt just to fix this
without any problem. I need to fix this asap please.

Thanks so much.

The MBR tells the computer which partition to boot from. A partition is a distinct area of the disk that is assigned as drive "C". If the computer has a drive D, and perhaps drives E and F, then the hard drive is divided up into partitions. If it only has one partition, then the CD-ROM drive is assigned the drive letter D.

Looking into it further.. it would be a bit easier and safer to use a repair disc that you could get online...

Iam getting scared to use the commands at command prompt as it will Wipe the whole disk.

Is there any other alternative to this. I mean any freeware or any other software which can fix
incorrect MBR.

I can go into windows. Only thing is some of the programs
are not working. At startup it is showing MBR Incorrect and thereafter it is entering Windows.
I can work on some of the programs after entering Windows. Only concern is not all programs
are not working.

Thanks again

Ohh.. if you can go into windows this that's amazing... Try a windows update... and all optional updates... and a windows reiar (Find and fix options)... windows should have picked up that there is hdd issues, and a update could fix this issue, with the bonus of not loosing your data...
