"disk boot failure insert system disk and press enter"

Okay, I know there are several threads on this topic already, but none of the solutions has helped me, which is why I'm making another one.

Anyways...
I just built my computer and everything in it is new except a hard drive with windows 7 installed on it.

It booted up fine, and loaded that hard drive just fine.

Besides the one hard drive, I have an additional hard drive and a SSD that I want to set up.

The computer recognizes both, so so far so good.

I turn off my computer and unplug the old hard drive, so that when I attempt to install windows 7 on the new ones, it won't change anything.

When I try to turn the computer back on, it displays "disk boot failure insert system disk and press enter".

I don't understand why. I've tried going into the bios setup and changing the boot first to the hard drive instead of the cd rom, and vice versa.. but nothing.

What am I doing wrong? :(

  1. Is there a setting in your BIOS named AHCI and if so, try changing it to IDE or SATA. If that doesn't work, try going back to Default Settings, disconnect the new drives and see if you can go back to the original system.

    Sorry, but what do you mean by "see if you can go back to the original system"?

    I meant the original Windows 7 system that I understood worked alright when it was the only hard disk in the box.
