Solution 2:

OK I looked up this error on the Microsoft website and it only happens when there is a failed install like yours, a failed uninstall, damaged file systems, a hard boot(meaning holding the power button until the PC turns off), incomplete formatting of the drive or a virus that was previously on the disk. If your drive is new and you have another PC handy try to plug that drive into the other PC if you can and format it completely and then try to install Windows 7. If that doesn't work I would contact Microsoft for help. I hope this helps.

Solution 3:

Note that the below will erase all data from your hard disk. Make sure this is what you want.

Boot from the Windows 7 DVD. After the Windows files load into memory, the Windows logo should splash onto the screen. Select the language to install and select "repair your computer". Since the system doesn't have any Windows OS installed, skip must of the screens until you access the "System Recovery Options" window. Select "Command Prompt". The system files are installed on the X: drive and your hard drive is D: since the Windows starting files were loaded on C:. Format the D: drive using the command

format D:\ /V

Answer Y to the warning message and verify the hard drive doesn't have errors. After formatting the hard drive, restart the system and try the Windows installation again.

Solution 4:

Simply run chkdsk to allocate new sector for the data which is located on bad sectors.

Use the command prompt type following commands

chkdsk [name_of_drive][path] /f /v /r /x

Examples:

C:\Windows\system32>chkdsk d: /f /v /r /x

or

C:\Windows\system32>chkdsk d:\anyFolder\anyfile.txt /f /v /r /x
