Remove Dual boot + Gnome, Keep W7?

I have a Dual boot machine with W7 and Ubuntu. Grub is controlling them. I have 100gb HDD partioned into 4 pieces (Boot/w7/Linux/swap). I am no longer interested in having the Linux stuff on it. I believe i can boot with my Grub disk and reallocate the partitions to W7, but I know that it will kill my boot manager. Can someone point me in the right direction to get one large partition with my currently installed W7. Even though i'm quite versed in full wipes/re-installs I currently work away from home 5.5 days a week, and would like to NOT take the time involved in a full re-install.

Thank you very much.

boot into windows 7. download EasyBCD from http://neosmart.net/download.php?id=1.

then go to your start menu and type partition and hit enter. Using the partition manager that will come up delete all of your partition except windows 7, and extend your windows 7 into the new free space. DO NOT RESTART YET!!!

Then open EasyBCD and go down to "BCD Deployment" and click it. Then hit write MBR, and you will be set.

:O I've totally forgotten about EasyBCD. Thanks a ton!

Awesome! it worked perfectly. Thanks SO much Wolfeking.

I know of easybcd to rewrite the mbr but is there an alternative to doing it?

booting to the Windows disk and using it to repair the MBR, but EasyBCD is the easiest and most pain free way.
