Remove “Choose an operating system” from startup

I want Windows Server 2012 to start quickly when I boot.

When I turn on my computer I see a screen like this:

Choose an operating system to start, or press tab to select a tool:
(Use the arrow keys to highlight your choice, then press ENTER.)

Windows Server 2012
Continue with install process

Windows Server 2012 starts automatically after 30 seconds. If I don’t want to wait that long I have to press enter.

If I choose Continue with install process, I see a screen like this:

Windows failed to start. A recent hardware or software change might be the cause.
1. Insert your Windows installation disc and restart your computer.
2. Choose language settings, and then chick “Next.”
3. Click “Repair your computer.”

If you do not have this disc, contact your system administrator or computer manufacturer for assistance.

This is all that’s left of almost installing Debian on my laptop. I thought this would be gone when the Windows Server 2012 installer formatted my hard drive, but I guess the boot record is stored in a special place that survives the format.

The rest of this post describes how to remove the screen and start Windows automatically.

Start Command Prompt as Administrator and run bcedit.

C:\Windows\system32>bcdedit

The output shows Windows Server 2012 as the only entry.

Restart the computer to go through the boot process again.

The computer should now boot Windows without a prompt.
