Windows 7: Problem with startup repair - no OS detected

Problem with startup repair - no OS detected

Hi.
Yesterday my laptop crashed and I had to shut it down on the button. When I turned on the windows started to loading files and went microsoft corporation loading and then appeared a black screen with only the cursor in the middle.
I searched and I used my Windows 7 usb to get into the startup repair. However, no OS was available. When I clicked to load some controller files (since there wasnt any OS listed), I could access my partition d, and the size was just normal. However the partition c (where the Windows 7 was installed) was with 0 of size and I couldn't access it.
Then I tried to do diskpart to activate the partition but no disk was listed.
If I try to install a clen Windows 7, it asks for a controller.
Can someone help me please? I'm panicking right now because I had some university works there and I don't know what to do
Thanks in advance.

It sounds like an older Notebook I recently worked on and the onboard [on the motherboard] HDD controller had failed, kept giving a 'check cable' warning. There is no IDE cable in a Notebook, the drive plugs into a socket on the motherboard.

I put the HDD in a USB box I use and was able to see and retrieve their files. They opted for a new Notebook instead of getting a motherboard which couldn't be found as new, only as refurbished or used.

Is the hard drive detected in BIOS setup? If not you can try reinstalling it to see if it will be detected, or replace it.

You can google a video or tutorial on how to reinstall or replace the hard drive or read the Manual on the Support Downloads webpage for your exact make and model number.

If the HD is detected then run the maker's HD Diagnostic
extended CD scan to determine its condition with certainty.

If it checks out OK work through the other steps for Troubleshooting Windows 7 Failure to Start

Welcome to Seven Forums.
This may work for you, download and make a bootable CD with this tool Partition Wizard Bootable CD allows user to manage partition directly with partition manager bootable CD.

Then try this to recover the partition. How to perform lost partition recovery and deleted partition recovery under Windows? Partition Recovery Help.

An alternate method to try to access the Windows install is: http://www.sevenforums.com/tutorials...ml#post2121339 You can save any data you find and do a reinstall of w7.

Thank you guys.

The computer was working for many years and the HDD is detected by BIOS I guess, because if I use any partition software it gives me information about the partition I had. Also, if I try to install Windows XP, it shows me partition 1 (unkown) and the size, and my partition 2, with the name NTFS and size.

I will try to do what Britton30 said.

I have done the lost partition recovery and I got what the image attached shows.

The first partition was my old (and existing) local disk c:, however the name and label was removed, and the last one is my local drive d:, named HB.

I'm able to search the content inside HB but I can't do it for the first partition which was the local disk c: where I had Windows 7 installed.

Now what can I do? Is there any way to fix the first partition? Why can't I access it?

Thank you very much.

It would appear the first 5 identical partitions are gone. Wait for Greg to have a look, he's better at recoveries than I am.

When you booted into Partition Wizard were your partitions displayed intact before running Recovery Wizard?

Please post a screenshot of the Partition Wizard drive map and listings showing all columns and drives

Yes they were, I could saw my two partition. The one that I can't acess (and that is on the top of the list of my previously screenshot) and the partition named HB, that I can search the content.

Right now I'm not able to make a screenshot, hope it helps anyway.

Thank you.

Can you right click the C partition in PW to Explore files?

When we see the screenshot we can help more.
