I get this BOOTMGR is missing message when I try to start up a Lenovo T61 with Windows Vista. I tried to use a boot tool that I got when I Googled MIGR-62978. It asks if I want to repair, I say yes. Then it says SafeGuard Easy was not found on this computer and the program did not make any changes. Then remove media and reboot. When I reboot, I'm back at BOOTMGR is missing. Any advice?
