If anyone stumble upon this thread when searching for "BOOTMGR is missing" and have a similar setup (2 hds SATA / ATA), I fixed the problem (well, not really fix) the hard way: removing the ATA (second) hd. Surely the second HD had a wrong MBR / GTP table / partition...

I didn't touch anything but suddenly I cannot boot in Windows 7 or Ubuntu on my MacBook Pro (Santa Rosa). The message is BOOTMGR is missing. My assumption is that my second hard drive is now the first hard drive, meaning that normally my 500GB is /dev/disk0, but now my 200GB is /dev/disk0. On Santa Rosa, my 200GB is connected with ATA and my 500GB is SATA, both use GUID Partion Table. How to...
