Windows 7: Cannot boot into Windows 7

Cannot boot into Windows 7

I had four partitions on my HDD. D,E,F for data and C contained Windows XP. Then I decided to install Win 7 due to some reasons. I thought that I would install Win 7 on my F drive and would format the C drive after that because the total size of C was very less. Windows 7 was successfully installed on F. Then I searched the web for removing XP, every result showed me a different way and I think I chose the wrong and formatted C drive completely.
After that, I was not able to boot any of the either OS and got the error on boot screen - "Remove Disk or any other media. Press any key to restart" "Reboot and select proper boot device or insert boot media in selected boot device".
Then I inserted Win 7 disk to solve the problem but the dvd drive doesn't recognise it to be a bootable disk and I was stuck to the black screen.
Now what I have is a newly installed Win XP to search for solution and which is directly booting without giving me a option to choose for Win 7.

How can I get back my Windows 7 and format C drive safely?
Can there be a solution without using the Windows 7's recovery console?
Thanks in advance!

First, follow the tutorial Partition - Mark as Active . For your current situation, it is better to follow the method three, and mark the partition containing windows 7 as active .

Next, run Startup Repair , it is better to run it 3 separate times with restarts .

If you cannot boot from your windows 7 disk, there is another way to do it, you may download repair disk. It should match your OS , I mean 32 bit or 64 bit.

EDIT : I guess you installed windows 7 running from windows XP . So the MBR was installed in partition C . When C is formatted, MBR is also deleted. Startup repair will add it to windows 7, and you are to mark the windows 7 partition as active to boot from it. I also guess you used 32 bit windows 7, if so, download the 32 bit version of repair disk .

I haven't noticed it at the first time. You should delete XP after marking the windows 7 partition as active ... otherwise the MBR will be added to XP partition again .

Thank you arc for your reply! Now what i hve to do is
1) Making the partition F as active.
Can I try method one from XP?
2) Create Repair disk and run Startup repair from it.
3) Then format XP.

One more thing I would like to tell you is that when I re-installed my windows XP, the F drive was renamed to G with all files at their place. I don't know how and I am sure that it was 'F' before the installation.
I think I had a pendrive(was named 'G' when XP showed me the current partitions) attached to my PC at that time and I had removed it in between installation.
Will it cause any further problems??

Unfortunately, if you mark F as active from C, it will make your C unusable. And you cannot make a windows 7 repair disk from XP. What you should do is ...

1. Download Partition Wizard Bootable CD and burn it.
2. Download repair disk and burn it .
Do these in XP.
3. Boot in Partition Wizard Bootable CD .
4. Mark F as Active , using method three.
5. Right Click on XP partition and delete it .
Do these in Partition Wizard. Save the changes, and exit from PW CD.
6. Boot in repair disk .
7. Run Startup Repair , for at least three times, with restarts after each single run.

That's it.

You have the pendrive attached then ?

Remove it, and when the operations will be completed, the current F should be named as C .

Later on, it will not be a problem to rearrange the other drive letters, if you want . There is a nice tutorial for it, http://www.sevenforums.com/tutorials...ndows-7-a.html .

Drive letters are not a serious issue, except the C drive . Changing the Letter of the C drive may make windows installation unusable; but for other drives containing data or other things (not system but anything), the maximum thing may happen due to changing the drive letter is the popping up of of the autoplay options window , and nothing else . You are not to be worried for it at all !

Now may I go to bed ? It's more than 2 AM already I hope you will be able to follow the steps properly .

At the morning, I will be there to see if everything went smooth or not
