What diagnostic program did you run?
I would like for you to run chkdsk /r. In order to do this we will use the instructions below for a Repair Installation.
Chkdsk /r checks for bad sectors on the hdd and recovers any readable information.
When you get to step 7b click on Command Prompt instead of Startup repair. When the Elevated command prompt opens type in chkdsk c: /r /x and then press Enter. Please note the spaces between chkdsk and c:, c; and /r, and /r and /x.
Let us know what the results are.
A Windows 7 Repair Installation will require a installation disc.
If you do not have a Windows 7 installation disc you can download a free legal ISO image of Windows 7 SP1 at Windows 7 Forums
. You will need to download the same version of Windows 7 that you have installed, This image is hosted by the Digital River store which is an official distribution partner of Microsoft. This is a genuine untouched image which is safe to download.
Attention: If you do have a Windows installation disc, skip Part A and go to Part B, Step 1b.
Part A, Steps 1a - 6a
The ISO image will need to be burned to a DVD in order to create a bootable installation disc.
1a) To burn a ISO file to a DVD please download ImgBurn
and install it.
2a) Insert a blank DVD into your CD/DVD drive tray, and then close the tray.
3a) Open ImgBurn, and click on Write image file to disc.
4a) Click on the Browse for a file icon:
5a) Locate the ISO file you want to burn, and click on the Open button.
6a) Click on the blue arrow to start burning the bootable DVD.
Please note: In order to boot from this DVD you may need to change the boot order in the BIOS so that the CD/DVD-ROM is the first device in the boot order, and the hdd is the second device.
Part B, Steps 1b - 10b
1b) Place the installation disc in the tray of the CD/DVD drive, close the tray and restart the computer.
2b) You will be prompted to press any key to start the installation, I find the space bar handy.
At this point the setup process will load files, this will take several minutes.
3b) You will now need to choose the Language, Time, currency format, and Keyboard or input method that you'd like to use.
After this is done click on Next.
4b) Click on the Repair your computer link at the bottom-left of the Install Windows window.
This link will begin the Windows 7 System Recovery Options.
5b) System Recovery Options will now search your hard drive(s) for any Windows 7 installations. This will take several minutes.
No participation is required on your part at this time, wait till it has finished and the next window opens.
6b) Choose the Windows 7 installation that you'd like to perform the Startup Repair on, then click on Next
7b) Click on the Startup Repair link from list of recovery tools in System Recovery Options.
For a future reference, there are several other diagnostic and recovery tools available in the Windows 7 System Recovery Options including System Restore, System Image Recovery, Windows Memory Diagnostic, and Command Prompt.
8b) The Startup Repair tool will now search for problems in the system files.
If Startup Repair finds a problem with any system files the tool may suggest a solution which you will need to confirm, or may solve the problem automatically.
9b) Startup Repair will now attempt to repair whatever problems it found with system files.
Note: If Startup Repair did not find any problems with system files you won't see this step.
Important: Your computer may or may not restart several times during this repair process. This is normal, you should allow it to continue until you see the Restart your computer to complete the repairs window.
10b) Click on Finish, this will restart your computer.
It is possible that the Startup Repair will not be able to fix the problem. If the Startup Repair tool determines this, it may automatically run the the repair after your computer restarts. If it does not automatically run the repair but you are still having problems with Windows 7 repeat these steps to run Startup Repair again manually.
