How do I remove the Linux Boot Loader?

You don't actually uninstall a boot loader but replace it with another.

You cannot get Ubuntu to start on a Windows' boot loader, it needs to be GRUB (or an open source equivalent).

Any ways, to get the Windows' boot loader back up, you need to insert your WIN7 installer disk and select the repair option>startup repair. I am assuming the WIN7 will use a similar setup menu as VISTA.

Follow the guide here for step by step intructions: http://neosmart.net/wiki/display/EBCD/Recovering+the+Vista+Bootloader+from+the+DVD

After that, just format the partition/disk that ubuntu is on...
