Nothing is connected to my laptop.
Can't go to any safe modes.Tapping F8 not doing anything.Tried recovering my system with Vista recovery disc' with no luck.When I get to System Recovery Options screen,no systems come up.I tried trun System repair,get the same massage at the end.Tried to do restore points,get error message about not having any restore points.Is there a way I can restore it to factory settings with pressing some magic buttons?Or do anything else to get it to work.I must've spent at least 20 hrs trying to fix it,with no results.Thanks for any suggestions.

Hi Agnes15,
Thank you for visiting Microsoft Answers.
It seems that the Boot Configuration Data (BCD) is corrupted.
Microsoft has completely reengineered the boot environment for Microsoft Windows Vista to address the increasing complexity and diversity of modern hardware and firmware. One aspect of this reengineering is a new firmware-independent data store that contains configuration data that influences the boot process. This paper provides an overview of this configuration data - called boot configuration data (BCD) - and describes how to use the related tools to manage boot options.
Step 1
Perform chkdsk which will repair the bad sectors of the hard drive.
To do this, follow these steps:
1. Click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
2. Type chkdsk/ f, chkdsk/r, chkdsk/i, chkdsk/c in the commands listed below i.e. (/f, /r , /i, /c).
Step 2
Try to load BIOS to default and check if you have similar issue.
Step 3
I would suggest you to rebuilt BCD. To do this, follow these steps:
To run the Bootrec.exe tool, you must start Windows RE. To do this, follow these steps:
- Put the Windows Vista or Windows 7 installation disc in the disc drive, and then start the computer.
- Press a key when you are prompted.
- Select a language, a time, a currency, a keyboard or an input method, and then click Next.
- Click Repair your computer.
- Click the operating system that you want to repair, and then click Next.
- In the System Recovery Options dialog box, click Command Prompt.
- Type Bootrec.exe, and then press ENTER.
8. Type bootrec /RebuildBcd , and press Enter.

Our three week old Dell T160 server running windows server 2008 is experiencing the same issue.
The SAS 6i6 Controller failed, thus corrupting the mirrored pair.
Recommendation: replace your hard drive(s).
Drive 0, Media Error and Drive 1, in a failed status.

Hello
Both my wife’s and my laptop came with windows 7 preloaded on them so I don’t have CDs to boot from. My question is it possible to copy the Boot\Bcd file from her computer and install it onto a flash drive to boot my computer.
Thanks
