Normally booting up problems are caused but not limited to the following:
- Not shutting down the computer correctly.
- Accidental deletion of an important system file or changing a setting
- Virus/Malware infection
- Incompatible/unconfigured third party software or hardware.
Booting up in safe mode is an effective way of overcoming these problems and fixing them, letting you boot up normally.
To boot into Safe Mode in Windows 7 -
• Shut down Windows, and then turn off the power
• Wait 30 seconds, and then turn the computer on.
• Start tapping the F8 key. The Windows Advanced Options Menu appears. If you begin tapping the F8 key too soon, some computers display a "keyboard error" message. To resolve this, restart the computer and try again.
• Ensure that the Safe mode option is selected.
• Press Enter. The computer then begins to start in Safe mode.
• When you are finished with all troubleshooting, close all programs and restart the computer as you normally would.
To boot into Safe Mode in Windows 10 -
After a few failed attempts at booting up, Windows 10 will acknowledge this and give you some start-up options. One of these will be Safe Mode, and you may also want to try using "Start Up Repair".
Once you are in safe mode you can try a system restore.
• Go to Start
• Choose All Programs then Accessories, Systems Tools then finally choose System Restore.
• Click Next and choose to restore your computer to an earlier time (when it was working)
• The follow all the instructions and the computer will restart to an earlier time.
• Please note you will not loose any documents/files etc but you may need to reinstall any programs or software drivers you have loaded yourself.
If you are still unable to boot into Windows, a good option is to perform a fresh reinstall of Windows - and you can even make sure all of your important files are kept safe. Click here for instructions on how to reinstall Windows
