Windows Won't Start Up

Having Windows 7 refuse to start up can be a worrying situation since there's often now way of knowing whether or not your data is safe or whether the hard disk has failed until, if it's even possible, you repair the problem. Fortunately, Windows 7 provides a startup repair tool which you can access by using your original Windows 7 DVD or a startup repair disk. Startup repair disks can be created from within Windows, so it's always a good idea to have one handy. If you don't have your Windows 7 DVD handy, you can either borrow one from a friend or make a startup repair disk using a functioning computer. Try the steps below to see if you can solve the problem.

1 - Last Known Good Configuration
Before you attempt to use startup repair, there is one simple step which you should take. This is most likely to work if the startup problems only occurred after installing a new driver, Windows update or service pack.
Press F8 repeatedly once you've turned your computer on. You should be able to reach the advanced boot menu. If not, proceed to the next step.
From the advanced boot menu, choose "Last known good configuration" by scrolling down the list with the arrow keys and pressing Enter. Windows will attempt to restore the computer to a previous time.

2 - Using Startup Repair
Insert your Windows 7 DVD or startup repair disk. Turn on your computer and tap F8 on your keyboard repeatedly before Windows 7 attempts to boot up. You should reach the advanced boot options screen.
If this doesn't happen, you'll need to boot up from the Windows 7 DVD or startup repair disk. For this to work, you may need to change the BIOS settings so that the computer attempts to boot up from the DVD drive first, rather than the primary hard drive. Since all BIOS setup utilities are different, you may need to refer to your computer's manual for further details. On most computers, you can enter the BIOS by pressing F2 or DEL on your keyboard just after turning the computer on.
If you can reach the advanced boot menu, choose "Repair Your Computer." If you're booting from the DVD instead, wait for the Windows setup files to be loaded into the system memory.
When the System Recover Options screen appears, click the first option, "Startup Repair." Startup Repair will scan your computer and attempt to fix any problems. Click "Finish" when done.
You should try this process two or three times before giving up. If this still does not work, then you may need to perform a clean installation of Windows 7. You can try connecting the hard drive to another computer in order to salvage any data on it beforehand. Be aware that a clean installation of Windows 7 will remove all data on the drive.
