Windows 7 Won’t Start Up! How to Recover Data from it?

When your computer appears to power up okay, but Windows 7 won’t start up properly, you have to worry about losing all your important files, pictures of precious memories, backups for crucial data and hours of essay. A computer that won’t boot up is frustrating which mean that you lose all you data, but you can troubleshoot it easily by yourself! To help you get Windows started and Windows data recovery, there are some efficient solutions for you to choose.

Last Known Good Configuration

Restart the computer and when you see the message ‘Please select the operating system to start’ or hear the single beep, keep pressing F8 key until the Windows Advanced Options menu appear. If the menu doesn’t appear, restart your computer and try again.

Use the arrow keys on the keyboard to select Last Known Good Configuration feature and press Enter. This feature allows you to undo any changes that caused problems in the Current Control Set registry key, which defines hardware and driver settings. The Last Known Good Configuration replaces the contents of the Current Control Set registry key with a backup that was last used to start Windows successfully.

Keep in mind that you get only one shot with the Last Known Good Configuration feature. In other words, if it fails to fix your Windows on the first attempt, the backup copy is also corrupt.

Safe Mode

If it still won’t boot properly, reboot and go to the Advanced Options menu again. This time, choose Safe Mode and press Enter. Windows starting in Safe Mode automatically skips loading programs and hardware components and displays very primitive graphics. In 99% of the cases, it’ll fix the problem. If your computer starts up properly, uninstall programs you installed or undo any changes you made recently. Then, restart your computer normally.

System Restore

Another tool that might be helpful when computer won’t boot up is System Restore. System Restore runs in the background as a service and constantly monitors system-critical changes. When it detects an impending change, System Restore immediately makes backup copies called restore points. These restore points are usually created when programs are installed or a system driver is updated.

Once Windows XP boots into Safe mode, click Start > Programs > Accessories > System Tools > System Restore. Once you start it up you will be given the option to Restore My Computer To An Earlier Time and follow the prompts on screen to select a restore point.After it finish, System Restore will automatically reboot the computer to complete the process.

Therefore, if you have installed a program that has made your computer unstable, the best way is System Restore. In addition, if you lose files and need to get them back, you can recover files after system restore with Windows 7 data recovery software like Tenorshare Data Recovery Standard. It can retrieve lost data after deeply scan your hard drive to look for lost data due to system sabotage, system restore, virus attack etc.

Recovery Console

If the above ways fail, then you have no choice but to use Windows CD which has a very useful tool called Recovery Console to repair your Windows.

Boot from the Windows CD by inserting it in the optical drive and restart your computer. When you see the Welcome to the Setup menu, click R to start the Recovery Console and select the operating system you want to repair. At this moment you may need to enter your administrator password.

The partition boot sector and the master boot record are essential for Windows to boot. If they are damaged by virus or configuration changes, Windows 7 won’t start up.

Fixing the partition boot sector is easy as the built-in fixboot utility will help you write a new partition boot sector and overwrite the existing one to fix this part of the system. Type “fixboot” and press Enter. After it is completed, reboot your computer.If you suspect the master boot record is also damaged then you can also fix it through another command – Fixmbr. If you have only one hard drive in your computer, type “Fixmbr\Device\HardDisk0″ and it’ll do the trick.Last but not least, make sure that you back up your registry table before making any changes and know how to restore as well.

If you lost files that you want to keep, data recovery software can recover them. But please note, once your files are overwritten by new data, they are gone for good.
