I would like to update the video card settings to allow aero mode on Windows 7 in Virtual Box but on the installation it says windows is in safe so aero mode won't work.

How do I take it out of safe mode?

  • Run msconfig and go to the Boot tab. If "Safe boot" is checked, uncheck it and reboot. If not, let us know, because something is very wrong.

  • It was already unchecked. There is something wrong.

  • Run SFC /SCANNOW from an admin command prompt and restart when done to see if SFC corrects the issue

  • Run: (1) chkdsk, (2) sfc /scannow, (3) verify disk SMART data by a utility such as Speccy, (4) Check the Event Viewer.
