Unable to get into Windows Safe Mode
Make sure you are entering Safe Mode properly. The Safe Mode menu can easily be missed if not done properly.
If the Safe Mode menu loads, but gives an error, restarts, or never loads when choosing the option your computer has a corrupt Windows system file or there is a hardware issue.
If you have recently added any new hardware to the computer, we first suggest you remove that new hardware to make sure it is not the cause of your issue.
If no new hardware was added to the computer, or removing the hardware does not resolve the issue, either Windows is corrupt or pre-existing hardware in the computer has gone bad. To resolve or locate the cause of this issue, we suggest that you erase the computer hard drive and reinstall Windows.
Although you could reinstall Windows over the top of the existing installation of Windows on the computer, we highly recommend you erase the hard drive and start over. Not only will this help test your hard drive, but this also removes any potential corrupt programs, viruses, or malware from the computer that could have caused or contributed to the issue.
If you encounter errors during the reinstall with copying files or errors formatting the hard drive, it is likely the hard drive is failing or has already failed. If Windows was able to successfully reinstall, it was likely Windows was corrupted and reinstalling everything has corrected the issue. Other hardware that may cause problems include the memory or power supply.
