Disable startup recovery

In case you find yourself in a situation where you need to keep a computer connected as a server, and it for some power outages only automatically enters the boot recovery screen (as was mine

case), follow the procedure:

There are two options, to disable boot recovery and to ignore errors during boot (avoiding logging in but keeping active if necessary to use).

You will need to enter CMD with administrator privileges, you can do this by looking in the CMD start menu and right-clicking on it and selecting "Run as administrator".

Ignore startup failures

bcdedit /set {default} bootstatuspolicy ignoreallfailures

In this way, failures that occur during startup progress will be ignored and the next time the computer is started, it will not enter the recovery screen automatically.

Disable Startup Repair

bcdedit /set {default} recoveryenabled No

Thus, the only way to recover the system should be with the Windows installation DVD or with a pen-drive that installs the system. To return to the previous state, simply change "No" to "Yes".
