Hi,

I have a dell laptop which was running windows 7 and one day it stopped booting up. A black screen appears saying "no operating system found".

I have very less knowledge of PC hardware stuff. I googled and below is what i tried.
Windows repair -
1)The windows repair shows MBR as corrupted. When i ran bootrec /fix mbr, i got "a device attached to this computer is not functioning".
2) DISKPART
a) list disk shows 2 disks, 1 with status online. Both disks have size 0 B.
b) list volume shows 2 volumes Volume 0 and Volume 1. Volume 0 is listed as healthy
c) list partition says no partitions.

Ubuntu live CD -
I logged on to the system using ubuntu live CD.
1. The disk status shows the Hard drive as healthy but one bad sector present.
2) sudo fsck /dev/sda says "ïnvalid argument while trying to open /dev/sda".
3) sudo fdisk -l lists nothing.
4) sudo badblocks -svn /dev/sda says "invalid starting block (0):must be less tha 0"



I have some important data on the hard disk which i want to recover/backup. I read in a lot of posts that the user backed up the data or recovered the data.

Please help. Any help would be appreciated. Thanks.

Sounds like a HD is dead, and you can try a few free recovery tools, but odd's are it's probably beyond that now, and needs a professional data recovery service, which usually start at hundreds up to thousands of dollars, and with no promise they will be able to recover anything off it.

Now, go back in time, buy an external drive, a usb stick, or sign up for all the free cloud services, or email yourself, all those "important" files you need. If it's that important, at least 2 copies of it should exist. None of these options will come close to costing the 500-1000 it will cost to get the data back.

Data backup is free->cheap. Recovery is not.

You can try it and see. There is no way to say this tool or that tool is going to work with your particular drive and the exact damage it has. It's hit and miss. Most recovery software is good, if you just deleted the folder, or just formatted it, etc. Physcial damage is hard for some free tool on the internet to fix. It can, but odd's are, it may be toast.
