Computer wouldn't start windows after being left in safe mode

Safe mode is a diagnostic mode of a computer operating system (OS). It can also refer to a mode of operation by application software. In Windows, safe mode only allows essential system programs and services to start up at boot. Safe mode is intended to help fix most, if not all problems within an operating system. It is also widely used for removing rogue security software.

Try tapping F8 from a cold start and see if you can start windows in safe-mode. If it is a Windows machine. Please advise if your machine does not use Windows or what happens, as to whether the system starts in safe-mode.

Here is a guide on how to start a Windows computer in safe-mode:

Have you tried uninstalling the drivers in safe mode ?
1.
You should print these instructions before continuing.
They will not be available after you shut your computer down in step 2.
2.
Click Start and then click Shut Down.
3.
In the drop-down list of the Shut Down Windows dialog box, click Restart, and then click OK.
4.
As your computer restarts but before Windows launches, press F8.
On a computer that is configured for booting to multiple operating systems, you can press F8 when the boot menu appears.
5.
Use the arrow keys to highlight the appropriate safe mode option, and then press ENTER.
6.
If you have a dual-boot or multiple-boot system, choose the installation that you need to access using the arrow keys, and then press ENTER.
Note
•
If Windows launches before you can choose a safe mode, restart your computer and try again.
•
In safe mode, you have access to only basic files and drivers (mouse, monitor, keyboard, mass storage, base video, default system services, and no network connections). You can choose the Safe Mode with Networking option, which loads all of the above files and drivers and the essential services and drivers to start networking, or you can choose the Safe Mode with Command Prompt option, which is exactly the same as safe mode except that a command prompt is started instead of the graphical user interface. You can also choose Last Known Good Configuration, which starts your computer using the registry information that was saved at the last shutdown.
•
Safe mode helps you diagnose problems.
If a symptom does not reappear when you start in safe mode, you can eliminate the default settings and minimum device drivers as possible causes.
If a newly added device or a changed driver is causing problems, you can use safe mode to remove the device or reverse the change.
•
There are circumstances where safe mode will not be able to help you, such as when Windows system files that are required to start the system are corrupted or damaged.
In this case, the Recovery Console may help you.
•
NUM LOCK must be off before the arrow keys on the numeric keypad will function.

Turn on the computer and begin hitting the "F8" key when you see the BIOS screen.

This will take you to the Safe Mode menu.

Use the arrow keys to highlight "Safe Mode," then hit "Enter" on your keyboard.

This will boot your computer in Safe Mode, a minimalist manner of operating Windows that runs only essential Windows files.

If using Windows XP in Safe Mode, click the "Start" button and then click "Run." In the box that pops up, type "msconfig" and hit "Enter."

If using Windows Vista or Windows 7, click the Windows logo in the bottom left corner of the screen, type "msconfig" in the search field and then hit "Enter."

This will open the System Configuration Utility.

In the System Configuration Utility box, click the "Services" tab, check the box that reads, "Hide All Microsoft Services," click "Disable All" and then click "Apply."

In the System Configuration Utility box, click the "Startup" tab, click "Disable All" and then click "Apply." Next, click the "Close" box.

A box will pop up that prompts you to restart your computer.

Select "Restart" and let the computer restart itself, allowing it to boot to Windows normally.

If the computer still stalls when trying to boot to Windows, restart the computer and boot to Safe Mode again.

Run your antivirus program in Safe Mode, deleting any files that are flagged as viruses, spyware or malware. Restart the computer and boot to Windows normally

hope this helps

Start your computer in safe mode

Safe mode starts Windows with a limited set of files and drivers. Startup programs don't run in safe mode, and only the basic drivers needed to start Windows are installed. For more information, see What is safe mode?

Safe mode is useful for troubleshooting problems with programs and drivers that might not start correctly or that might prevent Windows from starting correctly. If a problem doesn't reappear when you start in safe mode, you can eliminate the default settings and basic device drivers as possible causes. If a recently installed program, device, or driver prevents Windows from running correctly, you can start your computer in safe mode and then remove the program that's causing the problem. For more information about troubleshooting problems in safe mode, see Diagnostic tools to use in safe mode.

1. Remove all floppy disks, CDs, and DVDs from your computer, and then restart your computer.
   Click the Start button , click the arrow next to the Shut Down button , and then click Restart.

2. Do one of the following:
   

   • If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you'll need to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer.
     

   • If your computer has more than one operating system, use the arrow keys to highlight the operating system you want to start in safe mode, and then press F8.
     

3. On the Advanced Boot Options screen, use the arrow keys to highlight the safe mode option you want, and then press Enter. For more information about options, see Advanced startup options (including safe mode).

Please take time to rate me

No, it's not the boot.ini, without it you wouldn't get the boot options screen.
What you have is corruption - a critical file from Windows has been damaged or destroyed by a virus. Since you are no longer able to boot your only option left is to perform a full reinstall - get your recovery cd or an Windows install disk and follow the procedure.

Power on or Restart your computer, keep tapping F8 on the keyboard while it boots up. After few seconds, you'll be taken to the "Advanced Boot Options" with "Safe Mode" in the lists. Use the Up-Down arrow keys to highlight the "Safe Mode" and press enter on the keyboard to confirm the selected boot options. Black Screen with white texts will be displayed on the display, wait for few seconds until you see the windows logon Screen. You'll also see a confirmation message box asking you to confirm to boot into Safe Mode, click "yes" or "Ok" and proceed forward. There now you are in the Safe Mode.

If you need further help, let me know.

Good luck.
