Let me begin by saying I think Mint 12 is a terrific OS, which I am using on several computers. But I have computers on which I use Music Bee in Windows 7 for my music files and want direct boot to Windows without any disk space devoted to Mint. I spent several days looking at complicated instructions for removing Grub and finally accidentally discovered a simple solution, which is as follows: In Windows, download Partition Wizard at MiniTool Partition Wizard Home Edition - Download.com Install. Partitioning will be blocked by Grub. But on your left hit Rebuild MBR. This will take only a few seconds. Reboot, and Windows 7 will boot. Then you can go into Partition Wizard and eliminate the Ubuntu partitions and expand your Windows data partition to take up the freed up space.
