How to fix MBR


Hi all,
can someone help me. While installing RHEL6, i forget to choose the option Primary Boot Option from external hard disk and now i am unable to boot my Windows Professional from my internal harddisk. Whenever I want to start my Windows, everytime I have to plug my external hardisk and then select Other option to start my windows. I think this is the problem of MBR but i don't know how to restore back to my internal hardisk. Also i don't have Windows prof CD/DVD. Please help me its so frustating to plug and take external hardisk everytime whenever n wherever i need to start my laptop(Dell).
Thanks

Boot into Windows, start the Command line and launch the following commands:
For 2000/XP:
Code:
fixmbr
For Vista/7:
Code:
bootrec.exe /fixmbr

Thanks TobiSGD,
I have tried all these options but there is a message "'bootrec.exe' is not recognized as an internal or external, operable program or batch file ". What is the next option i can try. Please help me.

Besides Hirens BootCD you can use your Windows DVD. Start from it, launch the terminal from the repair mode, use the same commands.

It doesn't have to be a Windows 7 Professional, any Vista/7 DVD will do the job. You can download an evualation version of Windows 7 Enterprise here: http://technet.microsoft.com/en-us/evalcenter/cc442495

Automated repair should fix it. Boot to the dvd. As TobiSGD says almost any real Windows dvd would work or parts of on a usb. A neighbor or friends should work to do repair.
