I am trying to install Windows 8 Consumer Preview, but I get the following error:

Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1. Insert your windows installation disc and restart your computer.
2. Choose your language settings, and then click "Next".
3. Click "Repair your computer."
If you do not have this disc, contact your system administrator or computer manufacturer for assistance.

Status: 0xc0000260 Info: An unexpected error has occurred.

Before Windows 7 is reset, the Windows 8 Setup shows:

“We couldn’t install Windows 8 Consumer Preview. We’re not sure what happened, but we couldn’t finish installing Windows 8 Consumer Preview. We’ve set your PC back to the way it was.”\

What does the message mean? Can I install windows 8 consumer preview? Thanks.
