Help need... Lost boot sector while partitioning for linux kali

I have a laptop with win 7 professional. I have a 500 gb hdd with four partitions, c,d,e,f. Windows was installed in c.
As i wanted to install linux kali i needed a partition. I used gparted tool in live linux to create a partition 'h' drive of e drive, as mentioned in tutorial for linux dual boot. Then i proceded for hdd installation of it. But when it came to partition whr to install there was no h drive over there. So i quit the installation an booted in windows. Even in windows h drive dint showed up. So i opend partition manager and it showed there as unallocated. So i formated it. And then it showed as a drive in my computer. So i restarted again and proceded with linux installation. And again this time when reached to install on a partition, h drive was missing. This time my f and c drive was also missing. It showed only two drives d and e. And some how e drive had the capaciy of both e and f drive. I closed the installation again and restarted .. and now i am stuck at the boot . Bothing happens. Only a black screen comes with a cursor blincking. Nothing happens after it.
Tried repairing win 7 with dvd, but nothing happened. In windows recovery option there is no os to select.

Kindly help.

Drive letters can change in boot mode, this is normal. Judge the partition by its size and any label you gave.

In this case however if you saw differently sized partitions during the install, something must have gone wrong with your partitioning using the Linux (not Windows) tool.

Now you need help recovering Windows, so let's use Windows tools.

Using Diskpart or Partition Wizard CD as shown in this tutorial confirm that the 100mb System Reserved (if you have it) or Windows 7 (if you don't) is Partition Marked Active.

Then run Startup Repair - Run 3 Separate Times until Win7 starts.

Next post back a screenshot of Disk Management - Post a Screen Capture Image telling us what you'd like to do, and so we can confirm the configuration.

If this fails post back a camera snap of Partition Wizard drive map showing all listings and what you think is installed on each partition.

Ok... Will do the same and follow up

I tried the first step which was selecting the partituon and marking it active. But it failed i guess.
I have attached the screen shoot. Under list partition it shows 3 partition. Partition 1 i am not sure about. Partition 2 seems to be my c drive ,where windows was installed. And partition 3 seems to be my d,e, and f drive combined. How that happened, i have no idea. I used to have 4 diff partition. And a 20 gb partition wch i made few days back for linux.

I don't see the screenshot. Please attach picture using paper clip icon in reply box.

If the first partition is 100mb System Reserved then you would mark it Active, otherwise try the Win7 partition and then run Startup Repair - Run 3 Separate Times.

Partition Wizard CD would give us a better picture.

I have posted the screen shot with this, of diskpart where it dint go through.

Obviously you have a failing disk so you cannot now mark the 100mb System Reserved Active and run Startup Repairs to recover from the Linux disaster.

What to do now is to test the hard drive with the maker's HD Diagnostic
extended CD scan followed by a full Disk Check to find out its exact condition and possibly replace it.

If it passes diagnostics, then you can attempt to rescue your data at any time by booting into the WIn7 disk to browse for it using Copy & Paste - in Windows Recovery Console. Not seeing any data will strongly suggest its ruined.

If you can get the data then I'd wipe the drive with Diskpart Clean Command then try a full disk partition format following the commands to create, full format and mark Active in Step 2.2 of SSD - HDD Optimize for Windows Reinstallation. If it then passes Disk Check you can reinstall to the partition you created.
