HP laptop Win7 os black screen with blinking cursor when booting...

I compressed the hard drive on my, HP nc6120 notebook, the next day I cut laptop on & got a black screen that says NACDM is compressed Press Ctrl+Alt+Del to restart; but all it does is come back to the same screen. I created a repair disc from another PC tuning Win7, put the disc in tried system restore no change, tried repair fix start up it says no problems found and does nothing else. Didn't have any problems till I compressed the hard drive trying to save space. Can anyone help or at least tell me what NACDM means?

Try the same steps here to uncompress C drive which makes Win7 unbootable: BootMGR Compressed Message at Boot Fix - Vista Forums
