Can't boot without OS DVD in drive.

Installed upgrade from XPHome/sp3 to Windows 7 Home Premium.  (custom inatall)  My problem is:  I can't boot without the OS dvd.  When I try to boot, a message saying "Windows can't start" to correct the problem, do a repair.  I did and no change.  I then did a custom install, same result.  on the boot mgr page the info. is
Status:  OXC000000F
             file missing or corrupt.
File:  \$windows.~bt\windows\system32\winload.exe
Oh yes, in disk mgr., C: is system drive.  When I did the repair, it shows the correct drive but the drive letter is
E:  (I have four hard drives)  only one OS system.

Any help and suggestions will be appreciated very much.

PS:  I have a second computer that I upgraded and all is well.  I do like Windows 7. (when it works)

You might have to rebuild the Boot Configuration Database (BCD). To do that follow the below mentioned steps:

To run the Bootrec.exe tool, you must start Windows RE.

1.     Press a key when you are prompted.

2.     Select a language, a time, a currency, a keyboard or an input method, and then click Next.

3.     Click Repair your computer.

4.     Click the operating system that you want to repair, and then click Next.

5.     In the System Recovery Options dialog box, click Command Prompt.

6.     Type Bootrec.exe, and then press ENTER.

7.     Next line bootrec /RebuildBcd, and then press Enter.


Note To start the computer from the Windows Vista or Windows 7 DVD, the computer must be configured to start from the DVD drive. For more information about how to configure the computer to start from the DVD drive, see the documentation that is included with the computer or contact the computer manufacturer.
