Start up options

There are a variety of start up options available that may help repair the computer (or at least diagnose it).  Windows 8, 10 do not have the start options shown under Windows 7 (discussed shortly), so you may have to boot using an operating system disk (nice going Microsoft).  Check with the manufacturer too, there may be other boot options.

Windows 8, 10

If your computer stops the boot process at the sign in point, you may have a chance to restart to do some diagnostics/troubleshooting.  To do this, hold the shift key down, click the power button (lower right), while still holding shift, click restart and continue holding until reboot (when the screen goes black).

It should then restart in the diagnostics/repair options where you should see at least these choices:

But we've seen Windows 10 stuck in a startup loop repairing things that never completes and because we could not even get to a point to reboot in the troubleshooting mode, there was no other alternative than doing a factory restore.

Windows 7

Windows 7 has an easy option called Repair but you need to get to that menu first.  Get the boot menu:

Note: The mouse does not work instead use the cursor control (arrow) keys on the keyboard.  The startup menu will include the below list and maybe other things.

In the command prompt in (repair mode) you can do a lot of different things but a couple things that may resolve problems are listed below.  But first for giggles Log to the root drive, typically C: but may be another drive letter. 

Commands (more someday)

Safe mode

In the safe mode the video drivers are not load so your Desktop colors will appear terrible.  Don't worry, this occurs in the safe mode and will return to normal upon reboot (Start > Shut Down > Restart).

Now that you're in the safe mode, you can do whatever diagnostics are needed, e.g., run scandisk, defrag, disable start up programs, etc.  When you are done doing whatever simply reboot.

Safe mode with networking

Like above but you will be able to use the network hardware, i.e., get to the Internet.

Safe mode with command prompt

Places the computer immediately in a command prompt where you can run various DOS commands.  You can also type explorer followed by enter to start the Windows interface in the safe mode.
