Fixing MDR without using the Windows 7 DVD

I have deleted my old Ubuntu from my hard disk and as i know i cant go back into windows because Boot record is lost. I forgot that i dont have the windows 7 any more so i cant restore it the normal way. Is there any tool which i can burn on a CD/DVD to boot into to restore my MBR?

Any help would be great. Thanks.

So here is the MS link for reloading the MBR, since you have had grub, you can either do a deep clean, which others will know about then run the auto-repair. Or just run the commands in the link. I have gone back and forth between Ubuntu and W7 several times loading each boot-loader to make sure this works.
How to use the Bootrec.exe tool in the Windows Recovery Environment to troubleshoot and repair startup issues in Windows

You will need to boot with your Vista/Windows 7 installation disk. Hit Enter at the language selection prompt then hit "R" to get to the repair section. You can then select the automatic boot repair tool, but it often will not do any good. Then select the command prompt (console) and type in the following commands:

BootRec.exe /fixmbr
chkdsk /r
BootRec.exe /FixBoot
BootRec.exe /ScanOs
BootRec.exe /RebuildBcd

Use the recovery CD from neosmart that was posted.

I have gotten it to work every time with just these, but it wont hurt to run them all if needed
BootRec.exe /fixmbr
BootRec.exe /FixBoot

All of those commands and tests are automated in Win7 Startup Repair.

However if your booted Repair console does not show an installation to repair, you can sometimes force it to show by using the bootrec commands.
