Once such an error occurs, you're going to suffer from disasters as follows:

# Your computer has been affected by a virus or malicious software.
# Your Windows new updates have failed to install properly on your computer.
# The endless Startup Repair loop, taking a long time for checking your system for problems.
Your PC has run into problems such as operating system files corruption or misconfiguration.

Try Safe Mode When "Your computer was unable to start" hangs and takes forever to check problems

Usually, when this happens for the first time, just wait for the Startup Repair utility checking the problem for you. If the checking process goes smooth, largely, it's because the computer shut down improperly.

If a reboot didn't work, and it takes forever for Startup Repair to check the problem, maybe you have a corrupt driver. In this case, please try to boot up into Safe Mode.

Follow the steps to boot the computer in Safe Mode with networking:

Restart your computer if it is powered on.
Tap the F8 key after your computer initially powers on.

  1. 1. Once you see the Advanced Boot Options menu you can stop tapping.
  2. 2. Use the up/down arrow keys to highlight your selection.
  3. 3. Select Safe Mode with Networking and press Enter.
  4. 4. You should see drivers loading, and then please wait.
  5. 5. You should then be at the Welcome Screen.
  6. 6. Log on to your computer using an account with Administrator privileges
