I had a great setup for dual boot with Grub as my boot manager. I had Vista 64 and Ubuntu on two different drives. Today I installed the Windows 7 Beta on a third drive and it loaded the Windows Boot Manager to select between Vista and 7. I reset Grub to my MBR but when I select Vista it loads the Window Boot Manager. I would like it to boot Vista. I setup an entry for 7 but it fails to load since their is no boot record on that drive. Windows 7 was relying on the windows boot manager to boot. How can I get rid of the windows boot manager and get a boot sector on to the windows 7 drive so grub can be my boot manager again.
Thanks for any assistance.
